2-Alkyl derivatives of butane-2,3-diacetal (BDA) protected glyceraldehyde were stereoselectively prepared by aza-Claisen rearrangement of N-allyl-enammonium ions or C-alkylation of enamines. This allows rapid and convenient access to densely functionalized chiral building blocks.
通过N-烯丙基-铵离子的氮杂-克莱森重排或烯胺的C-烷基化来立体选择性地制备丁烷-2,3-二缩醛(BDA)保护的甘油醛的2-烷基衍生物。这样可以快速方便地访问密集功能化的手性构建基块。
