Abstract A new phospholipid synthesis has been developed. Phosphorylation of a 1, 2 diacylglycerol with the monofunctional reagent R 1 R 2 POCl (R 1 and R 2 being phosphate- protecting groups) provides a phosphotriester in 70–90% yield. Removal of one protecting group affords a phosphodiester, which is condensed with the required alcohol to a second phosphotriester (70–75% yield, based on the first triester). Subsequently, the other ...
