Efficient C(sp3)–H Bond Functionalization of Isochroman by AZADOL Catalysis
摘要:
A novel organocatalytic C(sp(3))-H bond functionalization of isochroman under practical conditions has been developed. In the presence of 5.0 mol % of AZADOL, the catalysis proceeded successfully with a broad range of substrates and nucleophiles in excellent yields.
As a part of our study on the reactions of 1-ethoxyisochroman (1) with nucleophilic reagents, the reactions of 1 with amines, amides, thioamides, sulfonamides, urea, thiourea, and heterocyclic compounds were examined.
