Tropylium-Catalyzed O-H Insertion Reactions of Diazoalkanes with Carboxylic Acids
Empel, Claire,Nguyen, Thanh Vinh,Koenigs, Rene M.
, p. 548 - 553 (2021/01/26)
Herein, we describe the application of a nonbenzenoid aromatic carbocation, namely tropylium, as an organic Lewis acid catalyst in O-H functionalization reactions of diazoalkanes with benzoic acids. The newly developed protocol is applicable to a wide range of diazoalkane and carboxylic acid substrates with excellent efficiency (43 examples, up to 99% yield).
One-Pot Reaction of Carboxylic Acids, Ynol Ethers, and m-CPBA for Synthesis of α-Carbonyloxy Esters

, p. 6423 - 6426 (2019/08/21)
A novel one-pot reaction of carboxylic acids, ynol ethers, and m-CPBA for the synthesis of α-carbonyloxy esters in the presence of Ag2O is described. This process provides a direct approach to α-carbonyloxy esters with the achievement of format
