acid derivatives is the base-catalysed elimination of a 4-(substituted) hydroxy group to generate a Δ4,5 pyranose. Following hydrogenation, proceeding mainly from the α-face provided the anomeric configuration is β, the initial C(5)-configuration is restored. This sequence affords access to a number of 4-deoxypyranoses: thus 4-deoxyglucoses are readily available by reduction at C(6). Conversion to a
