Nickel catalyzed asymmetric synthesis of dienyl sulfoxides were accomplished with up to 98 % ee from both racemic allenyl carbonates and β-sulfinyl esters employing cheap Ni(II) as precatalyst. Experimental and computational methods revealed an interesting associated outersphere mechanism which is uncommon in transition metal catalyzed asymmetric allylic nucleophilic substitution reactions.
使用廉价的 Ni(II) 作为预催化剂,由外消旋烯基碳酸酯和 β-亚磺酰酯完成镍催化二烯基亚砜的不对称合成,ee 高达 98%。实验和计算方法揭示了一种有趣的相关外层机制,该机制在过渡金属催化的不对称烯丙基亲核取代反应中并不常见。
