Nineteen racemic ring A substituted analogues of the antitumor agent 20(S)-camptothecin were prepared by total synthesis and evaluated for in vitro cytotoxic activity against KB cell culture and in vivo antileukemicactivity against L1210. These compounds bore a wide variety of substituents at C11 designed to confer upon the ring system a broad range of combinations of electronic, steric, and lipophilic
