Remote chirality control leading to 1,4-difunctionalized compounds such as 1,4-amino alcohols and 1,4-diamines was achieved by both syn- and anti-selective asymmetric Mannich reactions of α-thio acetaldehydes, the subsequent olefination and the stereospecific 2,3-sigmatropic rearrangement.
通过α-硫代乙醛的syn和anti选择性不对称Mannich反应,随后的烯化反应和立体专一性的2,3-重排反应,实现了对1,4-二官能团化合物(如1,4-氨基醇和1,4-二胺)的远程手性控制。
