title: A new route to the synthesis of cyclitol derivatives.
abstract: 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.
