TH190A - Acetophenone replaced by a group of substances - Google Patents

Abstract

The dirivative process of acetophenone was replaced by a mass. Which has the general formula as follows (chemical formula), when R1 is the hydroxyl radical, the phosphonoids radical C, amino glycosyl oxy Which may be added to acyl, benzyl oxycarbonyloxi, aryl carbonyl radical Substituted or irreplaceable C, trialkyl ammonioacyloxi or furoyloxi radicals, R2 and R3 are each atomic alkoxi radical. Less carbon and r4 are benzimidazole, furyl radicals or thienyl radicals. Which may be replaced With alkyl radicals with less carbon atoms, or phenyl radicals Which may be replaced by alkyl radicals with low carbon atoms, alkyl radicals with low carbon atoms, alkyl Ho, alkyline dioxie, acetyloxi or Al radical Coccyx Alcoxy Drug Patents
