The photocycloaddition of dimethyl acetylenedicarboxylate (DMAD) to carbon-carbon multiple bonds to give cyclobutene derivatives has been of considerable interest, and its reactions with aromatic umlecules have been successfully used for the synthesis of cyclooctatetraene derivatives 2 .
## Abstract In Order to decrease the ground state reactivity and increase their potential for [3+2] cycloadditions, cyanoβ and methoxyβcarbonylβsubstituted nitrones 1a and 1b, respectively, were prepared and irradiated in the presence of electronβrich alkenes such as 2 to afford the corresponding o
