Abstract

The invention comprises compounds of the general formula <FORM:0685403/IV (b)/1> wherein R stands for an alkyl or acyl group and X represents a chlorine or bromine atom. These compounds are made by reacting a compound of the general formula <FORM:0685403/IV (b)/2> with reagents of the formula ZOX wherein X represents a chlorine or bromine atom and Z stands for hydrogen or an alkyl group. In examples (1) and (3) 2,5-diethoxy-3-hydroxy-4-chloro-tetrahydro furane is obtained from 2,5-diethoxy-2,5-dihydro-furane, and (1) tertiary butyl hypochlorite, or (3) hypochlorous acid; (2) 2,5 - diacetoxy - 3 - hydroxy - 4 - chlorotetrahydro-furane is obtained from 2,5-diacetoxy - 2,5 - dihydro - furane and tertiary butyl hypochlorite; (4) 2,5 - diisopropoxy - 3-hydroxy - 4 - chlor - tetrahydro - furane is prepared from 2,5-diisopropoxy-2,5-dihydrofurane and tertiary butyl hypochlorite; (5) 2,5-diethoxy - 3 - hydroxy - 4 - brom - tetrahydrofurane is prepared from 2,5-diethoxy-2,5-dihydro-furane and hypobromous acid.
