  Synthesis of novel amino acid glycoside conjugates

  摘要：

  A new class of non-anomeric amino acid glycoconjugates can be prepared starting from either omega-amino- or omega-halodeoxyglucosides. Treatment of an ether-protected methyl 7-amino-6,7-dideoxy-alpha-D-glucoheptopyranoside with methyl aspartate isocyanate gave an urea-linked conjugate of methyl glucoheptopyranoside and aspartic acid. Nucleophilic displacement of the ether-protected methyl 6-chloro-6-deoxy-alpha-D-glucopyranoside with potassium succinimide followed by imide ring opening and amidation of the succinic acid monoamide with dimethyl iminodiacetate led to a conjugate of methyl 6-amino-6-deoxy-alpha-D-glucopyranoside and iminodiacetate bridged by succinate.
