【Abstract】 The 1,2:5,6-di-O-methylethylidene-D-mannitol has been prepared from D-mannitol with anhydrous zinc chloride as the catalyst. The optimum synthetic condition has been studied in detail and the yield of the reaction is 65%. Firstly, the product was oxidized by NaIO4 and then deoxidized by NaBH4 to yield (+)-1,2-O-isopropylideneglycerol. Furthermore, the outgrowths were analyzed and it was found that the outgrowths had no influence on the synthesis of the target compound.更多还原
