A new class of substituted γ-amino alcohols and downstream pyrrolidine derivatives have been synthesized successfully from simple 1-phenyl-ethylamine, in which a representative all-substituted pyrrolidine derivative with multiple stereogenic centers was obtained by highly diastereoselective [1,2]-Wittig rearrangement and intramolecular cyclization with perfect chirality transfer (up to >99.9% de) and
从简单的1-苯基-乙胺已成功合成了一类新的取代的γ-氨基醇和下游的吡咯烷衍生物,其中通过高度非对映选择性的[1,2] -Wittig获得了具有多个立体中心的代表性全取代吡咯烷衍生物。重排和分子内环化,具有完美的手性转移(高达> 99.9%de)和良好的收率。
