Alkylarylation of N-allylbenzamides and N-allylanilines with simple ethers for the direct construction of ether substituted dihydroisoquinolinones and indolines

摘要

A radical-initiated cascade addition and cyclization of N-allylbenzamides with simple ethers to construct ether-substituted dihydroisoquinolinones was performed in the presence of CuI. The cleavage of the sp(3) C-H bond in ether and the sp(2) C-H bond in phenyl was involved in this reaction. Moreover, the arylalkylation of N-allylanilines was also realized under similar reaction conditions, providing ether-functionalized indolines in good to moderate yields.
