Abstract

An enantiospecific route to the kainoids has been developed based on cobalt-mediated cyclization of N-alken-2-yl amino acid derivatives. ... It is well established that alkyl-cobalt(II1) species can undergo homolysis (thermal or photochemical) as well as p-elimina- tionsl (Scheme 1). We now report the application of the homolysis and p-elimination sequence to the enantiospecific synthesis of substituted pyrrolidine structures found in the kainoid group of natural products ...
