✦ Synopsis
Formyl-branched deoxy-sugars (Type B)2 have been accessible by two main routas. Ring contraction3 of a suitable aminopyrancside with nitrous acid gave C-form+deoxyfuranosides. Nucleophilic scission of sugar epoxides with either unsaturated organs-lithium reagants4, or with 2_lithio-1,3dithiane5, gave
