The intramolecular carbene C–H insertion of α-diazo-α(methoxycarbonyl)acetamides leading to β-lactams is effectively catalyzed by palladiumcomplexes. It is found that whereas Pd(0)catalysts typically produce mixtures of β-lactams together with Buchner-type reaction products, the use of Pd(II)-catalysts results in highly chemoselective transformations. According to DFT calculations, this insertion reaction

A B12-dependentenzyme, CarH*, was engineered that can efficiently catalyze the radical cyclization of halide substrates containing a pendant olefin or alkyne, enabling the synthesis of a series of α,α-difluorinated lactams. Additionally, CarH* displayed an intriguing ability to mediate reductive dearomative spirocyclization of substrates with aromatic acceptors to generate spirobicycles, featuring
AB 12依赖性酶 CarH* 经过精心设计,可有效催化含有侧链烯烃或炔烃的卤化物底物的自由基环化,从而合成一系列 α,α-二氟化内酰胺。此外,CarH* 显示出一种有趣的能力,可以介导底物与芳香族受体的还原脱芳香螺环化,生成螺二环,具有罕见的 1,3-环己二烯选择性。
