Oxiranyl remote anions from epoxy cinnamates and their application towards the synthesis of alpha,beta-epoxy-gamma-butyrolactones
A series of alpha,beta-epoxy-gamma-butyrolactones were synthesized in moderate yields via oxiranyl remote anions derived from epoxy cinnamate esters. The key synthetic step involved deprotonation of the beta-position of alpha,beta-epoxy cinnamate derivatives where the generated beta-anion was stabilized by remote chelation from an ester group. The substitution reaction of the anion with a variety of ketones, followed by cyclization, readily furnished the desired substituted alpha,beta-epoxy-gamma-butyrolactones. (C) 2020 Elsevier Ltd.
