The invention provides a process for preparing 11 β-hydroxy steroid dehydrogenase type 1 inhibitors of formula 2 via a catalyzed reaction between a compound of formula 1 and a compound of formula R2LG in the presence of base:
where R1, R2, X, Y, and LG are described in the specification. Exemplary catalysts contain palladium and one or more phosphine ligands. The process can be performed in a stereoselective manner to give enantiomerically enriched products.
该发明提供了一种制备11β-羟基类
固醇脱氢酶1型
抑制剂的方法,该方法通过在碱存在下,化合物1和化合物R2LG之间的催化反应制备公式2的产物,其中R1、R2、X、Y和LG在说明书中描述。示例催化剂包含
钯和一个或多个
膦配体。该过程可以立体选择性地进行,以给出对映体富集的产物。
