A new construction of unsymmetrically 1,4-disubstituted carbazoles has been devised and used in the synthesis of the alkaloid olivacine.The starting materials are gramines and the sodium salts of 2-cyano-4-oxopentanonitriles.These afford 4-cyano-5-(indol-

A new procedure for the synthesis of 3-acylcarbazoles useful for the construction of 6H-pyridocarbazoles is described starting from readily available gramines or indoles.This methodology is exemplified by a synthesis of the anticancer alkaloid olivacine.Some discrepancies are noted between our results and those of other authors.
