Claisen and related [3,3]-sigmatropic rearrangements have been well described as useful synthetic organic tools. Frequently, the [3,3]-sigmatropic rearrangements are combined with other reactions in a tandem sequence leading to the formation of sever

Enantiomerically pure α -substituted α -amino ortho-sulfinylphenylacetonitriles have been readily prepared by the reaction of diastereoisomeric mixtures of α -amino phenylacetonitriles with differently sized cycloalkenones and 2-methyl cyclopenten

In this work, we report the use of the asymmetric intramolecular Pauson-Khand reactions of 4-aryl-4-cyano-1,6-enynes for obtaining enantiomerically enriched bicyclo[3.3.0]octenones, and the influence of both the quaternary stereocenter and the sulfur

Enantiomerically pure pyrrolo[2,1-a]isoquinoline derivatives are obtained by 1,3-dipolar reactions of isoquinolinium azomethine ylides with enantiopure 3-p-tolylsulfinylacrylonitriles, tert-butyl (2E)-4,4-diethoxy-2-p-tolylsulfinylbut-2-enoate, and 5

The influence of the sulfinyl group as a chiral auxiliary in the stereoselective addition of oxiranyllithiums to (S)-2-p-tolylsulfinylbenzaldehyde has been studied. All reactions evolve with retention of configuration at the starting lithiated carbon

Enantiomerically pure alpha-substituted alpha-amino phenylacetonitriles have been readily prepared from 2-p-tolylsulfinylbenzaldimines following a two-step sequence: a moderately stereoselective hydrocyanation of the imines and a completely stereosel
