✦ Synopsis

Various 9-0-acyl derivatives of N-acetyl-and N-glycoloyl-neuraminic acid, and O-(5-acetamido-3,5-dideoxy-D-glycero-c-and -/3-D-gulucto-2-nonulopyranosylonic acid)-(2~6)-O-~-D-galactopyranosyl-(1~4)-D-glucopyranose were regioselectively synthesized by use of ortho esters. In addition, 5-acetamido-4-O-acetyl-D-glycero-D-galacfo-2nonulopyranosonic acid was prepared starting from the benzyl and methyl esters of N-acetylneuraminic acid. *Studies on sialic acids. VI.
