  The synthesis of neoglycophospholipid conjugates via reductive amination of ω-oxoalkylglycosides and phosphatidylethanolamines

  摘要：

  Phospholipid conjugates of mono- and disaccharides tethered with an n-decanyl spacer were efficiently synthesized via an improved reductive amination of deprotected omega-oxodecanyl beta-glycosides and phosphatidylethanolamines with or without alkenyl groups. The omega-oxodecanyl beta-glycosides were prepared by stereoselective glycosidation of glycosyl halides with l,10-decanediol followed by pyridinium dichromate oxidation. The acetyl groups of the omega-oxodecanyl beta-glycosides were removed with sodium methoxide prior to their conjugation with phosphatidylethanolamines. (C) 1998 Elsevier Science Ltd.
