Abstract
N-n-Butyl- and N-ethyl-isoindole react with dimethyl acetylenedicarboxylate to give rearranged 1 : 2 adducts, whereas with ethyl propiolate diethyl 3,3′-oxydiacrylate is obtained. Several 1,2,3,4,7-pentasubstituted isoindoles give 1 : 1 adducts with dimethyl acetylenedicarboxylate, and their failure to form 1 : 2 adducts is ascribed to steric effects.Keywords
