β-Elimination in aldonolactones. Synthesis of 3,6-dideoxy L-arabino-hexose (ascarylose)
Benzoylation of L-rhamnono-1,5-lactone (1) with an excess of benzoyl chloride and pyridine for 16 h afforded 2,4-O-benzoyl-3,6-dideoxy-L-erythro-hex-2-enono-1,5-lactone (2). Catalytic hydrogenation of 2 was stereoselective and gave crystalline 2,4-di-O-benzoyl-3,6-dideoxy-L-arabino-hexono-1,5-lacton...
