intramolecular hydroacylation has favored five-membered rings, in preference to four membered rings. Herein, we report a catalyst derived from earth-abundant cobalt that enables preparation of cyclobutanones, with excellent regio-, diastereo-, and enantiocontrol, under mild conditions (2 mol % catalyst loading and as low as 50 °C).
在过去的 40 年里,分子内加氢酰化有利于五元环,而不是四元环。在此,我们报道了一种源自地球丰富的钴的催化剂,能够在温和条件(2 mol% 催化剂负载量和低至 50 °C)下制备环丁酮,具有优异的区域、非对映和对映体控制。
