A glycoglycerolipid 1a isolated from a marine alga showed inhibition to Myt1 kinase with IC₅₀ of 0.12μg/mL. We synthesized 1a and its seven analogues (1b–h) in an efficient method with high stereoselectivity. The process employed trichloroacetimidate donor 4b at low substrate concentration to achieve high α-selectivity (α/β=33:1) in glycosylation reaction. The present synthesis provided various acyl derivatives required for the study on the structure–activity relationship later.
