α-Nitro olefins reacted with sodium benzenesulfinate in the presence of tertiary amine and palladium(0) catalyst to afford allylic sulfones. The competition experiment showed that relative rate of the sulfonylation of an α-nitro olefin to that of the corresponding allylic acetate was about 2.2.

We have found that (Z)-nitro olefins or mixtures of (E)- and (Z)-compounds can be converted to the pure (E)-isomers by treatment with catalytic amounts of triethylamine or polymer-bound triphenylphosphine, respectively. (C) 1998 Elsevier Science Ltd. All rights reserved.

We report a highly diastereoselective synthesis of vicinaldiamines by the treatment of nitroepoxides with primary amines and then a reducing agent. When using a chiral primary amine, racemic nitroepoxides are transformed into chiral diamines as a single enantiomers (>95:5 er) through a dynamic kinetic asymmetric transformation (DYKAT). The overall process is a one-pot procedure combining the exposure
