We report the preparation of enantioenriched secondary alkylcarbastannatranes via a stereoinvertive SN2 reaction of enantioenriched alkyl mesylates and carbastannatranyl anion equivalents. Using this process, enantioenriched secondary alcohols may be converted into highly enantioenriched alkylcarbastannatranes, which are useful in stereospecific cross-coupling reactions.
我们报告了通过对映体富集的烷基甲磺酸盐和碳原子化炔基阴离子等价物的立体转化S N 2反应制备对映体富集的仲烷基氨基甲酸酯。使用该方法,可以将对映体富集的仲醇转化为高度对映体富集的烷基碳黄烷烃,其可用于立体有择的交叉偶联反应中。

The invention relates to a novel process for the preparation of chiral 2-(4-aminophenyl) morpholines of the formula (I) wherein R1 is hydrogen an amino protecting group. The chiral 2-(4-aminophenyl) morpholines of the formula I are key intermediates for the preparation of compounds that have a good affinity to the trace amine associated receptors (TAARs).
