The Ramirez dioxaphospholen condensation: new access to branched-chain sugars
Abstract
The product of condensation of 2,3-O-isopropylidene-D-glyceraldehyde with 4,5-dimethyldioxaphospholen was hydrolysed to a free sugar which was converted by acidified methanol into a mixture of glycosides of 1-deoxy-3-C-methyl-D-ribo-hexulose.
