Abstract

An efficient method for preparing a series of polysubstituted cyclopentenones from TIPS- vinylketenes and Köbrich reagent has been developed in this paper. Additionally, highly substituted cyclopentenones can be prepared via [4+ 1] reaction of TIPS-vinylketenes with tert-butyl isocyanide and there is a remarkable preference for formation of products with an exocyclic (Z)-imine moiety.
