Abstract
An efficient approach for benzene-fused 6/7-membered amides via intramolecular amidation of aryl chlorides catalyzed by a Buchwald–Hartwig second generation Pd catalyst (Xphos Pd G2) has been successfully developed. This catalyst system allows the primary amides which have only modest nucleophilicity to be coupled successfully even with electron rich aryl chlorides in short reaction time. The intramolecular amidation reaction also has good chemoselectivity and excellent functional group compatibility.
