Book excerpt: Excerpt from Organic Seminar Abstracts: 1997-98, Semester I By definition, kinetic resolution is a separation of enantiomers and dynamic kinetic resolution involves equilibration of racemates with an inherent equilibrium constant equal to one. In the literature, however, the term is expanded to include the analogous process using mixtures of two diastereomers, which usually arise from placement of chiral, non-racemic auxiliaries onto racemates. Due to energy differences, the diastereomers may not be present in equal amounts in solution. Regardless, the process is typically used to resolve enantiomers, using the chiral auxiliary to direct the asymmetric transformation reaction with an achiral reagent. For example (scheme the diastereomers 1 arose from the reaction of (s)-2-oxoimidazolidine-4-carboxylate with a racemic substrate.4 Epimerization of the 2 bromopropanoyl group is base catalyzed in polar solvents; reaction with benzylamine gives a high yield and dr of 2.

Book excerpt: Excerpt from Organic Seminar Abstracts, 1970-1971: Semester II The an5 values of Table 2 are, as a group, more accurate than those re ported before, and partially for that reason the absolute values of these volumes are somewhat greater than those of Table 1. The near identity of the five quantities makes the conclusion unmistakable: there is no oh servable significant correlation in these systems between an5 and steric hindrance, and the differences noted.bef0re appear validly attributable to o participation with non-classical charge dispersion.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Organic Seminar Abstracts, 1979-80: Semester II Nature continues to provide a plethora of molecules which, for aesthetic, economic, and medicinal reasons, captures the attentions of synthetic organic chemists. Recently, efforts in many laboratories have focused on targets in the ansamycin, la polyether,1b and macrolide1c anti biotic families; these polyoxygenated molecules are rich in asymmetry and represent a formidable synthetic challenge to the imaginations and current methodologies of chemists. Many of these compounds have acyclic or macro cyclic structures which render them conformationally mobile. While stereo chemical control can be routinely achieved in the synthesis of conforma tionally immobile systems, stereochemical control in synthetic manipulations involving conformationally flexible molecules remains one of the unsolved problems in organic chemistry. The traditional strategy in synthesizing molecules such as these has involved controlling the stereochemistry by using conformationally unambiguous 5 or 6 - membered ring system precursors which can be ultimately opened and incorporated into acyclic or macrocyclic targets. The recent independent syntheses of the prelog-djerassi lactone by Stork2 and White3 and the macrolide syntheses by masamune1c and Corey attest to the power of such an approach. Much interest has been stimulated, however, in the control of stereochemistry in conformationally hetero geneous, acyclic systems. Many investigators have now begun to penetrate this largely unexplored region of organic synthesis and several novel solutions have been advanced. Some of these solutions will be discussed.

Book excerpt: Excerpt from Organic Seminar Abstracts: 1936-37 Karrer, by synthesis of four of the six remaining stereo isomers, as well as some twenty - five similarly constituted flavines, was unable to obtain any other compound showing vitamin activity. Apparently, due to steric hindrance, no structural isomers of lacto-flavine with the methyl groups in any but the -positions could be obtained. An interesting observation by Kuhn in this respect is that -dimethyl alloxazine has a lower oxidation - reduction potential than any of its isomers or homologs.
