A new method for the synthesis of the cardiolipin family of phospholipids which are characteristically located at the inner membrane of mitochondria, and particularly abundant in the heart, is described in this paper. A 1,2-diacyl-sn-glycerol, derived from stearic, palmitic, or myristic acid, is converted into the corresponding 1',3'-diphosphatidylglycerol (DPG), by means of the phosphorylating reagent
