title: Preparation of benzyl 2-benzyloxycarbonylamino-4-dichloroacetamido-2,4-dideoxy-alpha- D-xylopyranoside, substrate for the synthesis of the heterocyclic analogue of chloromycetin.
abstract: The paper describes the eleven stage synthesis of the derivative (XI) of 2,4-diamino-2,4-dideoxy-D-xylose, containing amino groups selectively substituted by two different acyls. The initial substrate was L-arabinose. The compound obtained, after removing the blocking groups, constitutes a semiproduct for the synthesis of the pyrrole analogue of chloromycetin by the Knorr method.
