Abstract: In this wrok, ethyl cephalotaxinyl oxalate was prepared by ester exchange and the synthesis of the key intermediate, α-keto-acetyl-cephalotaxine, was achieved by treating this oxalate with a Grignard reagent. This constitutes an efficient modification of previously reported mathods for the synthesis of cephalotaxus este ralkaloids.

Key words: Ethyl cephalotaxmyl oxalate, α-Keto-acetyl-cephaltaxme
