Both (E)- and (Z)-3-hydroxy-2-methyl-1-alkenyl iodides were stereoselectively synthesized from iodomethylated epoxides by treatment with sodium hexamethyldisilazane in DMF and with LDA in THF (or lithium 2,2,6,6-tetramethylpiperidide in THF), respectively.
(E)-和(Z)-3-羟基-2-甲基-1-烯基碘化物均由碘甲基化的环氧化物通过在DMF中用六甲基二硅氮烷钠和在THF中LDA(或2,2,6,6锂处理)立体选择性地合成-四甲基哌啶在THF中)。
