    • A novel process for producing 1,4-benzodioxane derivatives represented by general formula (1), which are useful as intermediates in the production of remedies for circulatory diseases and psychoneurotic diseases, comprising sulfonating a phenoxypropanediol compound by reacting with a sulfonyl halide compound, eliminating the protecting group, treating with a base to thereby subject to a ring closure reaction followed by, if required, further sulfonation. In said formula R represents H or RSO2 (wherein R represents alkyl or optionally alkyl-substituted phenyl); and R , R and R represent each H, halogeno, OH, NO2, CN, formyl, COOH, alkoxycarbonyloxy, alkyl, alkoxy, haloalkyl, N,N-dialkylamino, alkylcarbonyl, alkoxycarbonyl, optionally alkyl-substituted phenyl, etc.
    • 一种用于生产由通式(1)表示的1,4-苯并二恶烷衍生物的新方法,其可用作生产循环系统疾病和精神神经病疾病的药物的中间体,包括通过与磺酰卤化合物反应来磺化苯氧基丙二醇化合物,消除 保护基团,用碱处理,从而进行闭环反应,随后如果需要,进一步磺化。 在所述式中,R 1表示H或RSO 2(其中R表示烷基或任选被烷基取代的苯基); R 2,R 3和R 4分别表示H,卤代,OH,NO 2,CN,甲酰基,COOH,烷氧基羰基氧基,烷基,烷氧基,卤代烷基,N,N-二烷基氨基,烷基羰基, 烷基取代的苯基等
