A REGIOSPECIFIC TOTAL SYNTHESIS OF ELLIPTICINE VIA NITRENE INSERTION

Miller, R. Bryan,Dugar, Sundeep

, p. 297 - 300 (2007/10/02)

Ellipticine, a 6H-pyridocarbazole alkaloid, has been regiospecifically synthesized by a general route which should allow for the preparation of a number of derivatives.The approach employs a versatile coupling reaction between phenylboronic acid and a substituted bromoisoquinoline followed by carbazole ring formation via a nitrene insertion reaction to give ellipticine.
