Lithiation of N-aryl S-alpha-alkylbenzyl thiocarbamates leads to rearrangement with migration of the N-aryl ring to the anionic centre alpha to S, a process which generally proceeds with ca. 98% retention of stereochemistry and returns chiral benzylic tertiary thiols in high enantiomeric ratios.
N-芳基S-α-烷基苄基硫代氨基甲酸酯的锂化会导致N-芳基环向阴离子中心α迁移至S的重排,该过程通常在大约20 98%的立体化学保留率,并以高对映体比例返回手性苄基叔硫醇。
