β¦ Synopsis
Sumnary: Amikacin and l-N-[(S)-4-amino-2-hydroxybutyryl]-3',4'-dideoxykanamycin B have been prepared from kanamycin A and dibekacin by a novel, efficient sequence of reactions involving complex formation with Zn2+ and regiospecific N-trifluoroacetylation using ethyl trifluoroacetate.

## Abstract A new and facile method of synthesis of 1βacetoxyvinyl phosphonates (__2__) has been found. Dialkyl phosphites react readily with acetic anhydride in acetonitrile solution in the presence of catalysts to produce __2__ and acylphosphonates (__1__) as a minor product. The most efficient c
