AgOTf-catalyzed three-component reactions of 2-alkynylbenzaldehydes, amines, and diethylphosphite. An efficient route to 2,3-disubstituted-1,2-dihydroisoquinolin-1-ylphosphonates.
AgOTf was discovered as a highly efficient catalyst in reactions of 2-alkynylbenzaldehydes, amines, and diethylphosphite, which provided a facile and efficient pathway for the synthesis of 2,3-disubstituted-1,2-dihydroisoquinolin-1-ylphosphonates.
