✦ Synopsis
3-Amino-3-cyano-3-deoxy sugars obtained by cyclization of dialdehydes with cyanoacetamide and Hojkann rearrangement were reductively decyanuted using sodium borohydn'de providing a new approach to 3-amino-3-deoq sugars.
3-Amino-3-deoxy sugars are components of aminocyclitol', macrolide', and anthracycline antibiotic?. The therapeutic value of these drugs has stimulated the development of diverse strategies"" for the synthesis of 3-amino sugars branched at C-3.
Recently, we have contributed4 in this field developing a methodology for the synthesis of 3-amino-3-cyano-3deoxy sugars type 3 by cyclization of dialdehydes obtained from sugars with cyanoacetamide and Hofmann rearrangement, as depicted in Scheme 1.
