Herein we describe a simple and practical protocol for accessing the 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.
