Abstract
The acid-catalysed reaction of 4,1',6'-trichloro-4,1',6'-trideoxy-galacto- sucrose (1) with 5.5 equiv. of 2-methoxypropene in N,N-dimethylformamide followed by acetylation gave 3',4'-di-O-acetyl-4,1',6'-trichloro-4,1',6'-trideoxy-2,3-O- isopropylidene-6-O-(1-methoxy-1-methylethyl)-galacto-sucrose (2, 2%), 6,3',4'- tri- O-acetyl-4,1',6'-trichloro-4,1',6'-trideoxy-2,3-O-isopropylidene-galacto -sucrose (3, 31%), 3',4'-di-O-acetyl-4,1',6'-trichloro-4,1',6'-trideoxy-2,3-O- isopropylidene- galacto-sucrose (4, 38%), 3'-O-acetyl-4,1',6'-trichloro-4,1',6'-trideoxy-2,3-O- isopropylidene- galacto-sucrose (5, 13%), and 2,3',4'-tri-O-acetyl-4,1',6'-trichloro- 4,1',6'-trideoxy-galacto-sucrose (6, 13%). Methylation of 4 followed by removal of the protecting groups gave 4,1',6'-trichloro-4,1',6'-trideoxy-6-O-methyl- galacto- sucrose (8). 4,1',6'-Trichloro-4,1',6'-trideoxy-3-O-methyl-galacto-sucrose (11) was synthesised from 6 by preferential tert-butyldiphenylsilylation of HO-6 followed by methylation and removal of the protecting groups. Likewise, 4,1',6'-trichloro- 4,1',6'-trideoxy-4'-O-methyl-galacto-sucrose (14) was synthesised from 5. Treatment of 3 with aqueous acetic acid followed by methylation and removal of the protecting groups afforded 4,1',6'-trichloro-4,1'6'-trideoxy-2,3-di-O-methyl- galacto-sucrose (17).

Abstract
A convenient sequence for the synthesis of 1-O-alkyl-2-O-alkyl'-sn-glycero-3-phospholipids was demonstrated starting from 2,3-O-isopropylidene-sn-glycerol, which was first alkylated with 1-bromohexadecane, then converted to the corresponding benzylidene analog. Other less convenient methods to prepare 2,3-O-benzylidene-1-O-hexadecyl-sn-glycerol were also investigated. The key step in the synthesis was the reduction of 2,3-O-benzylidene-1-O-hexadecyl-sn-glycerol with lithium aluminum hydride-aluminum chloride to give 3-O-benzyl-1-O-hexadecyl-sn-glycerol as the major product in 79% yield. The syntheses of 1-O-hexadecyl-2-O-hexadecyl-(1',1'-d2,-sn-glycero-3-phosphoethanolamine and 1-O-hexadecyl-2-O-hexadecyl-(1'-13C)-sn-glycero-3-phosphoethanolamine as well as the correspondingly labeled sn-glycero-3-phosphocholine analogs were then performed. The optical purities of the synthetic intermediates and the ether lipids were established by a novel 1H-NMR method.
