摘要
2-Alkynyl benzyl azides smoothly underwent an electrocyclic reaction catalysed by palladium to selectively afford either 4-bromoisoquinoline and 4-bromoisquinolones under different conditions. 4-Bromoisoquinoline was synthesised in the presence of PdBr2/CuBr2/LiBr in MeCN, and 4-bromoisoquinolone was selectively produced with PdBr2/CuBr2/HOAc in CH2ClCH2Cl. A bromine was introduced into the products which makes the methodology more attractive for organic synthesis.
