Abstract
A mixture DMSO–allyl bromide has been developed as a reagent for an atom economic one-pot N-allylation and aryl bromination under basic conditions. Utilizing this reagent, N-allylation–bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, and 7-aza indoles has been achieved. The scope of the substrates and limitations, the synthetic utility of the products, and a plausible reaction mechanism have been proposed.
A mixture of DMSO–allyl bromide–KOH has been developed as a reagent for one-pot N-allylation and aryl bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, 7-aza indoles has been achieved.![]()
