E. Ciganek et al., SYNTHESIS OF 1A-METHANO-11AH-BENZO[4,5]CYCLOOCTA[1,2-C]PYRROLES - A NEW HETEROCYCLIC RING-SYSTEM, Journal of heterocyclic chemistry, 32(5), 1995, pp. 1637-1638
The synthesis of the novel 1a-methano-11aH-benzo[4,5]cycloocta[1,2-c]-
pyrrole system by acid-catalyzed cyclization of l-3a,4,7,7a-tetrahydro
-1H-isoindole-1,3(2H)-diones is described.
