Book Synopsis Organocatalytic Michael Cycloisomerization by : Ronald Thomas Smith
Download or read book Organocatalytic Michael Cycloisomerization written by Ronald Thomas Smith and published by . This book was released on 2006 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The organocatalytic Michael cycloisomerization has been utilized in both methodological and synthetic chemistry by our research group. This paper investigates the extension of this methodology to other electron deficient alkenes, i.e. nitroalkenes, and their utility in the total synthesis of the classical organic target morphine. The problems and successes encountered en route to the synthetic target as well as the chemistry involved is discussed in detail herein.

This book was released on 2016 with total page 1130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The route to the key bicyclic intermediate was streamlined to eight steps in 16% yield, using a TMSI promoted coupling of a furan and an enone. Additionally, methodology for the selective ozonolysis of the bicyclic intermediate was developed via ozone titration. Work on the dihydroxylation step led to the discovery and development of a new pH-neutral Sharpless-style asymmetric dihydroxylation. The synthesis of pentacyclic core of citreamicin μ was accomplished in 12 steps. New methodologies were developed, including: an ortho- selective bromination of a vanillin derivative and the use of 4-(Phenylazo)diphenylamine (PDA) as an internal indicator for the acetylide coupling. The usefulness of PDA led to its development as a general all-purpose indicator for the titration of strong bases, Lewis acids and reducing agents. The discovery of (n-Bu)4NOAc as a privileged additive led to the development of new methods for the synthesis of isocoumarins and new methodology for the condensation of amino acids using LiMe4 was developed.
