| titleOfInvention | Process for producing 2-hydroxymethyl-2,3-dihydro-thieno [3,4-b] [1,4] dioxin |
| abstract | The present invention provides a method for producing 2-hydroxymethyl-2,3-dihydro-thieno [3,4-b] [1,4] dioxin which can be obtained in high yield without complicated purification. A reaction between 3,4-dihydroxythiophene-2,5-dicarboxylic acid dialkyl ester and halogenated propanol in the presence of a weak base, followed by 2-hydroxymethyl-2,3-dihydro-thieno [3]. , 4-b] [1,4] dioxin-5,7-dicarboxylic acid, or a mixture of its dialkyl ester, followed by hydrolysis with a strong base to obtain only the dicarboxylic acid form, followed by a copper catalyst To obtain 2-hydroxymethyl-2,3-dihydro-thieno [3,4-b] [1,4] dioxin of the formula by decarboxylation in the presence of [Selection figure] None |
