The Reaction of Ammonia with Acylated Disaccharides. VIII. Octa-O-benzoylmaltose and Benzoyl Derivatives of Maltose
Octa-O-benzoyI-β-maltose (I) was prepared and its reaction with methanolic ammonia produced 4-0-α-d-glucopyranosyl-1,1-bis(benzamido)-l-deoxy-D-glucitol (IIa), maltose (III), 6-O-benzoylmaltose (IV), and N-benzoylmaltosylamine (Va) isolated as its heptaacetate Vb. The structures of Ila and IV were e...
