Abstract

The photodecarboxylation reactions of -phthalimidoalkynoates have been studied and the influence of the geometrically restricted acetylene linker on the photocyclization efficiency investigated. Less flexible starting materials give solely CO2H/H-exchange products in good yields. In contrast, derivatives with appropriate chain lengths give the corresponding macrocycles in fair to moderate isolated yields. Furthermore, photodecarboxylative addition of alkynoates to N-methylphthalimide gives hydroxyphthalimidines in acceptable yields.
