Meeting the challenge: The first asymmetric catalytic C*P bond formation employing electrophilic phosphorus compounds has been developed using a catalytic amount of a dimeric cinchona alkaloid, and a subsequent one‐pot process to deliver high stereoselectivities and good yields of α‐quaternary α‐phosphino β‐amino acids (see scheme). 31P NMR experiments suggest a novel reaction mechanism wherein a
迎接挑战:使用催化量的二聚金鸡纳生物碱和随后的单锅法开发了使用亲电磷化合物形成的首个不对称催化C * P键的形成方法,该方法可实现高立体选择性和良好的α-四价α收率-膦基β-氨基酸(参见方案)。31 P NMR实验表明一种新颖的反应机理,其中金鸡纳生物碱亲核地活化了亲电磷。
