biologically active galactosyl ceramide KRN7000 and other α-glycolipids with excellent yield and stereoselectivity by using per-O-silylated galactosyl iodide and stannyl ethers as glycosylation partners. This direct glycosylation reaction reduces the overall number of steps and provides rapid access to biologically important α-galactosyl ceramide derivatives. (© Wiley-VCH Verlag GmbH & Co.
