Hydroxyalkylation-Initiated Radical Cyclization of N-Allylbenzamide for Direct Construction of Isoquinolinone
摘要:
A metal-free hydroxyalkylation-initiated radical six-membered heterocycle formation reaction of N-allylbenzamide is developed. This reaction proceeds through C(sp(3))H bond cleavage, oxyalkylation of the double bond, and intramolecular cyclization, which provides a new route toward 4-substituted 3,4-dihydroisoquinolin-1(2H)-one derivatives.

A metal-freeoxidative tandem coupling of N-allylbenzamide with aryl aldehydes was realized. This method allowed the 1,2-difunctionalization of the C═C double bond in N-allylbenzamides through simultaneous formation of two C(sp2)–C(sp3) bonds. In the presence of DTBP, 4-substituted 3,4-dihydroisoquinolin-1(2H)-ones were obtained in satisfactory isolated yields. 3-Substituted indanones could also be
