Catalytic asymmetric Pauson–Khand reactions with chiral bidentate phosphines as ligands have been successfully accomplished. The catalytic use of (S)-BINAP as a ligand was demonstrated to be the most effective in the cobalt-catalyzed reactions of 1,6-enynes, providing a facile entry to optically active 2-cyclopentenone derivatives with high enantioselectivity. A plausible mechanism for the asymmetric induction
以手性二齿膦为配体的催化不对称Pauson-Khand反应已成功完成。已证明(S)-BINAP作为配体的催化作用在1,6-炔烃的钴催化反应中是最有效的,可轻松进入具有高对映选择性的旋光2-环戊烯酮衍生物。根据获得的立体化学结果,提出了一种不对称诱导的合理机制。
