A process for the stereoselective synthesis of chiral 3-heterocyclyl-1,2-dihydroxy cyclohexanes is disclosed. The process involves reacting a tricyclic nitrogenous heterocycle with an allyl carbonate in the presence of a chiral palladium catalyst followed by oxidation of the olefinic bond to provide 3-heterocyclyl-1,2-dihydroxy cyclohexanes, cyclopentanes and corresponding alicyclic heterocycles. Also disclosed are methods for converting the heterocyclyl-1,2-dihydroxy cyclohexanes to 2-amino-6-(heteroaryl)cyclohexanols (and related cyclic compounds).
本发明公开了一种立体选择性合成手性 3-杂环-1,2-二羟基环己烷的工艺。该工艺包括在手性钯催化剂存在下,使三环含氮杂环与碳酸烯丙酯反应,然后氧化烯烃键,得到 3-杂环基-1,2-二羟基环己烷、环戊烷和相应的脂环杂环。还公开了将杂环烯丙基-1,2-二羟基环己烷转化为 2-氨基-6-(杂芳基)环己醇(及相关环化合物)的方法。
