Enantiomerically pure syn-1,2-diaryl-1,2-sulfanylamine derivatives can be obtained in a completely stereoselective manner by reaction of the benzylcarbanion Li-(S)-1 with N-phenyl (or PMP)-arylidene aldimines and further desulfinylation with t-BuLi. Theoretical studies at the DFT (mPW1PW91) level with the CPCM model, by using the Gaussian09 program, provide a good explanation for the stereochemical results.
通过苄基阴离子 Li-(S)-1 与 N-苯基(或 PMP)-亚胺的反应,并进一步用 t-BuLi 进行脱硫反应,可以以完全立体选择性的方式获得对映纯的顺式-1,2-二芳基-1,2-硫代氨基衍生物。使用 Gaussian09 程序,通过 DFT(mPW1PW91)理论研究与 CPCM 模型相结合,为立体化学结果提供了很好的解释。
