An efficient synthesis of both enantiomers of trans-3,4-bis(benzyloxy)cyclopentanone 4, potential precursors to the five-membered (A)-ring of the neocarzinostatin chromophore, was accomplished from diethyl tartrate in 7 steps.
以酒石酸二乙酯为原料,通过 7 个步骤高效合成了反式-3,4-双(苄氧基)环戊酮 4 的两种对映体,这两种对映体可能是新胭脂虫色素的五元 (A) 环的前体。
