38. Review: Synthesis of Cortisone
 
52:09
Freshman Organic Chemistry II (CHEM 125B) Discoverers of the structure and biological activity of steroid hormones won seven Nobel Prizes between 1927 and 1975. Studying the steps involved in Woodward's 1951 "total" synthesis of cortisone provides a review of the organic reactions covered this semester. Many steps involved novel insights, others were based on lore from previous work In the area. The overall yield of such sequential syntheses is typically much lower than that of convergent syntheses. Practical syntheses of cortisone were based on modification of related steroids readily available from nature. Milestones in total synthesis include both purely intellectual work with natural products and commercially important synthesis of designed pharmaceuticals. The course ends with thanks to those, young and old, who have taught us all. 00:00 - Chapter 1. Steroids and the Medicinal Activity of Cortisone 07:43 - Chapter 2.

This contemporary synthesis relies on organometallic chemistry and more advanced retrosynthetic disconnections. This part contains a short discussion of reaction mechanism. 18:10 Closing comments Tell me whether I should continue doing such videos and if so, whether I should focus on "easy" approaches or more advanced ones (or make two types of videos and do both of them).

What is ORGANIC SYNTHESIS? What does ORGANIC SYNTHESIS mean? ORGANIC SYNTHESIS meaning & explanation

What is ORGANIC SYNTHESIS? What does ORGANIC SYNTHESIS mean? ORGANIC SYNTHESIS meaning - ORGANIC SYNTHESIS definition - ORGANIC SYNTHESIS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Organic synthesis is a special branch of chemical synthesis and is concerned with the construction of organic compounds via organic reactions. Organic molecules often contain a higher level of complexity than purely inorganic compounds, so that the synthesis of organic compounds has developed into one of the most important branches of organic chemistry. There are several main areas of research within the general area of organic synthesis: total synthesis, semisynthesis, and methodology. A total synthesis is the complete chemical synthesis of complex organic molecules from simple, commercially available (petrochemical) or natural precursors. Total synthesis may be accomplished either via a linear or convergent approach. In a linear synthesis—often adequate for simple structures—several steps are performed one after another until the molecule is complete; the chemical compounds made in each step are called synthetic intermediates. For more complex molecules, a convergent synthetic approach may be preferable, one that involves individual preparation of several "pieces" (key intermediates), which are then combined to form the desired product. Robert Burns Woodward, who received the 1965 Nobel Prize for Chemistry for several total syntheses (e.g., his 1954 synthesis of strychnine), is regarded as the father of modern organic synthesis. Some latter-day examples include Wender's, Holton's, Nicolaou's, and Danishefsky's total syntheses of the anti-cancer therapeutic, paclitaxel (trade name, Taxol). Each step of a synthesis involves a chemical reaction, and reagents and conditions for each of these reactions must be designed to give an adequate yield of pure product, with as little work as possible. A method may already exist in the literature for making one of the early synthetic intermediates, and this method will usually be used rather than an effort to "reinvent the wheel". However, most intermediates are compounds that have never been made before, and these will normally be made using general methods developed by methodology researchers. To be useful, these methods need to give high yields, and to be reliable for a broad range of substrates. For practical applications, additional hurdles include industrial standards of safety and purity. Methodology research usually involves three main stages: discovery, optimisation, and studies of scope and limitations. The discovery requires extensive knowledge of and experience with chemical reactivities of appropriate reagents. Optimisation is a process in which one or two starting compounds are tested in the reaction under a wide variety of conditions of temperature, solvent, reaction time, etc., until the optimum conditions for product yield and purity are found. Finally, the researcher tries to extend the method to a broad range of different starting materials, to find the scope and limitations. Total syntheses (see above) are sometimes used to showcase the new methodology and demonstrate its value in a real-world application. Such applications involve major industries focused especially on polymers (and plastics) and pharmaceuticals.

Organic Electrolytic Synthesis
 
03:46
The Nishiyama Group is studying the synthesis of natural organic compounds using electrical energy. The aim is to synthesize compounds that are useful in medicine and other fields, and to enable environmentally friendly organic synthesis. Q: Our aim is to actually synthesize biologically active organic compounds that occur in nature. There are a wide variety of such compounds, ranging from quite complex to very simple. In particular, a feature of our research is that were using electrochemistry, or electrolysis, for environmentally friendly organic synthesis. Chemical synthesis using electrochemistry and electrolysis can be used to induce only the reactions needed, without producing toxic substances. Consequently, it is currently topical as a means of environmentally friendly chemical synthesis. The Nishiyama Group is breaking new ground internationally, through original organic electrolysis reactions using phenols. QOne current environmental problem is waste products that are organic halogen compounds. As these contain halogens such as chlorine or bromine, they are toxic, and they dont naturally decompose. But electrolysis can be used to remove the halogens.A feature of our research is that we synthesize organic compounds based on phenols. Benzene is easy to polymerize. But if you combine just two benzene rings,please clarify part about ether, or link benzene rings directly, then those compounds can be used, for example, to synthesize a chain of amino acids, which is strongly biologically active. So were doing quite original research on phenol chemistry, using electrochemistry for synthesis, as I mentioned earlier. For pharmaceuticals manufactured by organic synthesis, safety testing is extremely important. It can take over a decade to produce a single drug. Organic electrolysis reactions, which do not use toxic substances, are expected to be very safe, and to enable much faster development. For such research, the Nishiyama Group uses a special system to develop man-made biologically active substances that are more effective than natural organic compounds. QIn our study meetings, we have one team that makes the target substances using electrochemistry, and another team that makes complex compounds using standard chemical synthesis. The two teams can complement each other by bringing together their new discoveries and new technologies. For example, weve had several cases where standard chemical synthesis alone doesnt work, but electrochemistry can be used to find a more effective reaction at once. In that sense, we aim to achieve complete syntheses through both teams helping each other.

Joshua Pierce from NC State University presented a talk at the October 28, 2016 entitled "Marine Natural Products Synthesis: A Platform for Chemical and Biological Discovery" Abstract: Marine natural products often have complex structures and potent biological activities; however, little is understood regarding how their molecular structure correlates with function or what biological targets or pathways are involved. Through rapid and efficient chemical syntheses of bioactive marine natural products, we are able to prepare ample quantities of material to explore both structure-activity relationships as well as target identification studies. Specifically, the monanchocidin and synoxazolidinone families of natural products will be discussed, leading to novel synthetic derivatives that serve as lead structures for infectious disease and cancer chemical probe and therapeutic development.
