or ketones affords (E)-3-trimethylsilyl-2-alken-1,4-diols (2), which can be readily dehydrated to 3-trimethylsilyl-2,5-dihydrofurans (3) by treatment with BF3OEt2. The compounds (3) are converted to furans (5) by epoxidation and subsequent treatment with H2SO4.
将3-三甲基甲硅烷基-2-丙炔-1-醇(1)进行氢磁化,然后与醛或酮反应,可制得(E)-3-三甲基甲硅烷基-2-链烯-1,4-二醇(2),该物质易于脱水通过用BF 3 OEt 2处理得到3-三甲基甲硅烷基-2,5-二氢呋喃(3)。通过环氧化和随后用H 2 SO 4处理将化合物(3)转化为呋喃(5)。
