NOVEL AND EFFICIENT SYNTHESIS OF 5,8-DIMETHYL-9H-CARBAZOL-3-OL VIA A HYDROXYDEBORONATION REACTION

摘要

N-Protected carbazol-3-yl-boronic acid derivatives have been efficiently hydroxydeboronated under mild conditions by employing hydrogen peroxide.The method allows to easily obtain 3-hydroxycarbazoles as precursors of new analogs of the anticancer agent 9-hydroxyellipticine.
