An approach to 1-phosphorylated isoquinolines through silver(I)-catalyzed tandem reaction involving C–N and C–P bond formation

A novel silver-catalyzed tandem reaction of 2-alkynylbenzaldoximes with H-phosphinate esters, and H-phosphine oxides has been developed, providing a general and powerful tool for the synthesis of various 1-phosphorylated isoquinolins in moderate to excellent yield. This reaction proceeded smoothly to construct C–N and C–P bonds in one-pot with good functional group tolerance under mild conditions.
