Abstract:
The syntheses of four head group labeled analogs of 1,2-di-O-palmitoyl-sn-glycero-3-phosphocholine (DPPC) (6) by a general method from 1,2-di-O-palmitoyl-sn-glycero-3-phosphatidic acid (5) have been performed. The syntheses of 1,2-di-O-palmitoyl-sn-glycero-3-phospho[alpha-13C]choline (6a) and 1,2-di-O-palmitoyl-sn-glycero-3-phospho[beta-13C]choline (6b) were performed from labeled [1-13C]glycine (1a) in 52% overall yield and from [2-13C]glycine (1b) in 56% overall yield, respectively. 1,2-Di-O-palmitoyl-sn-glycero-3-phospho[N(C2H3)3]choline (9) was prepared from 2-aminoethanol in 39% overall yield. 1,2-Di-O-palmitoyl-sn-glycero-3-phospho[alpha-C2H2]choline (12) was prepared from N,N-dimethylglycine ethyl ester in 50% overall yield.
