Anti‐headache chemistry: In the presence of a tailored modular P,P ligand the nickel‐catalyzed addition of HCN, generated in situ from TMS‐CN, to styrene derivatives proceeds with an unprecedented level of stereocontrol (up to 97 % ee) to give 2‐aryl‐acetonitriles, for example, the depicted precursor of Ibuprofen.
抗头痛药的化学性质:在存在定制的模块化P,P配体的情况下,由TMS-CN原位生成的镍催化的HCN加到苯乙烯衍生物中,其立体控制水平达到前所未有的水平(ee高达97% )给出2-芳基乙腈,例如所示的布洛芬前体。
