Short Step Syntheses of Indolo[2,3-a]Carbazoles Carring an Alkyl, Allyl, or a Glycosyl Group at the 11-Position and a Novel 6,7-Dihydro-13H-Cyclopentano[mn]Indolo[3,2-c]Acridine Derivative

摘要

Novel 1-alkyl-, 1-allyl-, and 1-#beta#-glycosyl-2,2'-biindolyls are prepared. Their Diels-Alder reaction produced 11-alkyl-, 11-alkyl-, and 11-#beta#-glycosylindolo[2,3-a]carbazoles. Formation of a novel 6,7-dihydro-13H-cyclopentno[mn]indolo[3,2-c]acridine derivative is also reported.
