## Abstract Classical phospholipids syntheses were selected and adapted to the preparation of natural glycerophospholipids labelled with carbon 14 in the acyl moiety. 1,2‐(^14^C) diacyl‐3‐bromo sn‐glycerol was the starting material. Saturated ^14^C‐phosphatidyl‐ethanolamine, choline and serine wer

✦ Synopsis
Starting from 1-2 isopropylidene sn-glycerol, the synthesis o f mono and diglycerides labelled with 14C i n the a c y l moiety has been achieved.
The acyl chloride method was found t o be the best one f o r the e s t e r i f i c a t i o n step.
The various methods, here proposed with p a h i t i c or Zauric acid may be generaZized for the obtention of other saturated glycerides.
