Six derivatives of 10-hydroxycamptothecin were prepared via solvolysis of topotecan in corresponding alcohols and acetic anhydride. We attributed the specific reactivity of topotecan to the internal hydrogen-bonding between 10-hydroxy and the nitrogen atom in position 9. As a result the reaction underwent through an intermediate ortho-quionomethlide species to reach equilibrium. Bioactivity screening
