Three cyclitol derivatives, 2, 4/3-triacetoxycyclohexanone diethyl dithioketal (XVIII), and 2, 3, 4-tri-O-acetyl-1-O-ethyl-2, 4/1, 3-cyclohexanetetrol (XXA) and 2, 3, 4-tri-O-acetyl-1-O-ethyl-1, 2, 4/3-cyclohexanetetrol (XXB), have been synthesized via the cyclisation of 2, 3, 4-tri-O-acetyl-5, 6-dideoxy-D-xylo-hex-5-enose diethyl dithioacetal (XIV) and the cyclisation of 2, 3, 4-tri-O-acetyl-5, 6-dideoxy-D-xylo-hex-5-enose diethyl acetal (XV) under ultraviolet or direct sunlight, in aqueous acetone.
