Abstract
The rules of Hann and Hudson apply not only to the formation of benzylidene derivatives of sugar alcohols and pentose dithioacetals, but also to the formation of di- O-benzylidenepentose dialkyl acetals. Treatment of the dimethyl acetals of D-ribose, D-xylose, and D-lyxose with benzaldehyde and zinc chloride yields 2,4:3,5-di- O-benzylidene derivatives. D-Arabinose dimethyl acetal gives a 2,3:4,5-di- O-benzylidene derivative. The structures of these compounds were proved by their synthesis from the appropriate di- O-benzylidenepentose diethyl dithioacetals.
