A short synthesis of antitumor ether thioglycolipids: Thioglycosidation of a glucose donor with a tributylstannyl sulfide acceptor
摘要:
Efficient routes to alpha- acid beta-thioglucolipids 1a and 1b are described starting from 1-O-hexadecyl-3-O-(p-toluenesulfonyl)-sn-glycerol (2) in 72% and 68% overall yields, respectively. Deprotection of the S-benzyl group of the glyceride 4 with tri-n-butyltin hydride produced the tin derivative 5, which was glycosidated with a glucose donor.
