Functionalized tetrahydrospiropyran derivatives can be easily accessed regioselectively by the use of nitrostyrene derived MBH alcohols and 2‐arylidene‐1,3‐indanediones in high chemical yields (up to 93 % yield). The synthetic utility of MBH alcohol as an ambiphilic substrate towards the synthesis of spirocyclic skeletons is noteworthy.
通过使用硝基苯乙烯衍生的MBH醇和2-芳叉基-1,3-茚满二酮,可以以高化学产率(高达93%的产率)轻松地选择性地选择官能化的四氢螺并吡喃衍生物。值得注意的是,MBH醇作为螺环骨架合成的歧义底物的合成效用是值得注意的。
