THE REACTION OF 1,4-DIHYDROCYCLOPENTINDOLES WITH DIMETHYL ACETYLENEDICARBOXYLATE

Diethyl 1,4-dihydro-4-methyl-3-(N-methyl-3-indolyl)cyclopentoindole-1,2-dicarboxylate (3) reacted with dimethyl acetylenedicarboxylate (DMAD) in acetonitrile under reflux to give the 5,10-dihydrocyclopentindole (5).The same reaction in benzene gave the maleate (or fumarate) (6) and the 1,1a,3a,4-tetrahydrocyclobutcyclopentindole (8).Thermolysis of 8 resulted in the formation of 5.In contrast to a cycloaddition reaction of 3 and DMAD, 2 reacted with two molecules of DMAD to give the 1,1a,5a,6-tetrahydrocyclohexcyclopentindole (10).Keywords: 1,4-dihydrocyclopentindole; dimethyl acetylenedicarboxylate; cycloaddition; 5,10-dihydrocyclopentindole; tetrahydrocyclobutcyclopentindole; tetrahydrocyclohexcyclopentindole.
