PREPARATION OF HYDROXYL GROUP DERIVATIVE OF COMPOUND CONTAINING CARBAZOLE, DIBENZOFURAN OR DIBENZOTHIOPHENE GROUP

摘要

Hydroxyl derivatives of compounds containing a carbazole, dibenzofurane or dibenzothiophene group, such as ellipticine, are prepared by selectively intro­ducing an R³-CO group, in which R³ is hydrogen or alkyl, and then converting the R³-CO group into a hydroxyl group.
