Zinc-mediated Reductive Dimerization Cyclization of Ethyl Arylmethylidene cyanoacetates in Aqueous Media
Abstract
Zinc-mediated reductive dimerization–cyclization of ethyl arylmethylidenecyanoacetates occurs to give diethyl 2-amino-3-cyano-4,5-diaryl-1,3-cyclopentenedicarboxylates in moderate to good yields the trans, trans-form isomer being the major product.
