摘要:

Chemical investigation on the stems ofNothapodytes foetidahas resulted in the isolation of 9-methoxy-20-(S)-mappicine, a new minor constituent along with seven other known alkaloids. The structure of the new compound was established from spectral and chemical evidences. An efficient chemoenzymatic synthesis of the compound starting from 9-methoxycamptothecin, a known constituent of the plant, has been achieved.
