Ru(II)-catalyzed intermolecular ortho-CâH amidation of weakly coordinating aromatic ketones with sulfonyl azides is reported. The developed reaction protocol can be extended to various substituted aromatic ketones to afford a wide range of desired CâN bond formation products in good yields.
chemoselective double annulation of α-trifluoromethylated isocyanides with o-acylaryl isocyanides has been developed. This new reaction provides a rapid, efficient, and complete atom-economic strategy for the synthesis of trifluoromethylated oxadiazino[3,2-a]indoles in a single operation from readily available starting materials. Isocyanide insertion into C═O double bonds is disclosed for the first
已经开发出空前的α-三氟甲基化异氰酸酯与邻酰基芳基异氰酸酯的化学选择性双环。该新反应提供了快速,有效和完整的原子经济策略,可通过一次操作从容易获得的起始原料合成三氟甲基化的恶二嗪并[3,2- a ]吲哚。由18 O-标记实验的结果表明,异氰酸酯首次插入C = O双键。提出了这种多米诺反应的机制,其中包括两种不同异氰酸酯的化学选择性异二聚化,然后是吲哚-2,3-环氧化物的形成和重排。

An enantioselective copper‐catalyzed intramolecular borylacylation is reported. The reaction proceeds through an initial enantioselective borylcupration of the styrene, followed by a nucleophilic attack on the tethered carbamoyl chloride. The products, chiral borylated 3,3‐disubstituted oxindoles, were generated in excellent yields and enantioselectivities. The versatile carbon–boron bond provides

The reaction of alkene-tethered trifluoroacetimidoylchlorides with trialkylphosphites furnishes 1-amino-2,2,2-trifluoroalkylphosphonates. The products were generated in moderate to good yields, and the scalability of this process was showcased. Partial hydrolysis of the phosphonate moiety was achieved. The cyclization is proposed to occur via formation of an imidoyl phosphonate intermediate that
