The first cyclooligosaccharide of the L.-series, α-cycloawaodorin (1), was efficiently synthesized by an α-selective thermal rhamnosylation reaction in a stepwise process. A thiomethyl group at C-1 played a dual role as a protecting group during the thermal glycosylations and as an activator on cycloglycosylation.
