Abstract

Indolocarbazole 4 and arcyriaflavin A 19 reacted under basic conditions with 1-benzyl-2,6-bis (benzotriazolyl)-piperidine to give 5 and 20. As an extension of this methodology other related bis benzotriazole derivatives were synthesized and coupled with 19 to obtain a variety of aza derivatives 3. N-dbenzylation of these compounds gave novel PKC inhibitors.
