Photocycloaddition reactions of N-methylindoles to dimethyl acetylenedicarboxylate (DMAD) yield derivatives of cyclobutenes: 9,10-bis(methoxycarbonyl)-2-methyl-3,4-benzo-2-azatricyclo<3.3.2.0>deca-3,9-dienes.No secondary photorearrangements are prevalent, but ring opening of the formed cyclobutenes is effected at moderate temperatures.
