Useful enantioselective bicyclization reactions using an N-protonated chiral oxazaborolidine as catalyst.

Gang Zhou1, Qi-Ying Hu, E J Corey.   

Abstract

[reaction: see text] Nine examples are reported of enantioselective [4 + 2] cycloaddition reactions of achiral, acyclic substrates to form chiral bicyclo[4.3.0]nonane or bicyclo[4.4.0]decane derivatives.
