合成路线1
该中间体在本合成路线中的序号：(II)A synthesis of [14C]-labeled artemisin has been reported: The methylation of the ketal acid (I) with lithium diisopropylamide and [14C]-MeI in THF gives the methylated intermediate (II), which is then submitted to an oxidative cyclization with ozone in dichloromethane. The key intermediate (I) had already been obtained as an intermediate of a previously published total synthesis of artemisin (Avery, M.A. et al. J Amer Chem Soc 1992, 114: 974).
