摘要

Selective acylation of the phenolic hydroxyl group of 10-hydroxycamptothecin has been accomplished using phenyl dichlorophosphate. Additional modification of the 10-OH as an ether permits a 20-acyl derivative to be synthesized. This result along with data from a 6- hydroxyquinoline model strongly suggests that powerful intermolecular hydrogen bonding exists in the parent molecule.
