  • Title: Enzymatic glycosylation using 6-O-acylated sugar donors and acceptors: beta-N-acetylhexosaminidase-catalysed synthesis of 6-O,N,N'-triacetylchitobiose and 6'-O,N,N'-triacetylchitobiose.

    Abstract:
    p-Nitrophenyl 6-O-acetyl-2-acetamido-2-deoxy-beta-D-glucopyranoside (5a) was used as the glycosyl donor in a beta-N-acetylhexosaminidase-catalysed (from Penicillium brasilianum) glycosylation of GlcNAc yielding 6'-O,N,N'-triacetylchitobiose (6), while 6-O-acetyl-2-acetamido-2-deoxy-beta-D-glucopyranose (3a) served as a selectively protected acceptor in a transglycosylation reaction catalysed by the same enzyme to yield 6-O,N,N'-triacetylchitobiose (4).
