Abstract
An ISES (in situ enzymatic screening) lead pointed to conditions (PMP N-protecting group, Ni(cod)(2) catalyst precursor) under which chiral, bidentate phosphines could promote Ni(0)-mediated allylic amination. Therefore, bidentate phosphines bearing central, axial, and planar chirality were examined with two model substrates of interest for PLP-enzyme inhibitor synthesis. In the best case, with (R)-MeO-BIPHEP, vinylglycinol derivative 2 was obtained in 75% ee (97% ee, one recrystallization) from 1. Further manipulation provided a Ni(0)-mediated entry into l-vinylglycine. [reaction: see text]Entities:
