NEW PIRROLO 3,2-e]INDOL DERIVATIVES, PROCESS FOR THE PREPARATION THEREOF AND APPLICATIONS.

摘要

The new pirrolo [3,2-e]indol derivatives have the formulae (I), (Ia) and (II) wherein R is substituted or unsubstituted aryl or heteroaryl, R' is substituted or unsubstituted alcanoyl, alkenoyl, alkinoyl, arenocarbonyl or heterareocarbonyl and X is chloro, bromo, iodo or alkylsulfonyl or arylsulfonyl. The process comprises: (a) deacylating (VII) in order to obtain (VIII); (b) subjecting (VIII) to a cyclopropyl ring opening raction in order to give (IX); (c) reacting (IX) with acid R-COOH in order to yield (I); (d) optionally, reacting (I) with a base in the presence of a condensing agent in order to obtain (II); (e) optionally, reacting (I) with a carboxylic acid in the presence of a condensing agent or with an acid chloride in the presence of a base to give (Ia). The compounds (I), (Ia) and (II) find application as agents having antitimoral activity for the treatment of cancer. <CHEM>
