Expedient and Versatile Formation of Novel Amino-deoxy-ketoheptuloses

Abstract

Novel monoketoheptuloses have been synthesized employing an amination step in a <i>pre</i>- and/or <i>post</i>-<b>C1</b> chain elongation using a Petasis reagent by starting from aldohexoses or aldohexosamines. A series of <i>gluco</i> and <i>manno</i> configured 1-/3-deoxy-1-/3-amino-ketohept-2-uloses could be obtained
