Stereoselectivity of cycloglycosylation in mannooligose series depends on carbohydrate chain length: Syntheses of manno isomers of β- and γ- cyclodextrins
Syntheses of manno isomer of β- and γ-cyclodextrins were achieved for the first time employing methylthioglycosides of α-(1→4) linked mannoheptaose and mannooctaose.
