| titleOfInvention | 5-nitro-furfurylidene-amino derivatives |
| abstract | <FORM:1120652/C2/1> <FORM:1120652/C2/2> Novel compounds of the Formula I, in which X is -O- or -SO2-, R is an alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl or aryl group which may be substituted by one or more alkoxy or alkylsulphonyl groups, and n is 0 or 1, are prepared by reacting 5-nitrofurfural, or a reactive derivative thereof, with a compound of the Formula II. Starting materials of Formula II.-The compounds in which n is 0 are prepared by reacting 2-mercapto-ethanol with a 1,2-epoxy-3-(R-X)propane to give a thioether of formula HO.CH2.CH2.S.CH2.CHON.CH2-X-R, oxidizing and ring-closing this to form a 3-(R-X-CH2)-1,4-thioxane-1,1-dioxide and reacting this with hydrazine to form a 3(R-X-CH2) - 4 - amino - tetrahydro - 1,4thiazine - 1,1 - dioxide. 3,5 - Bismethoxymethyl4-amino - tetrahydro - 1,4 - thiazine - 1,1dioxide is prepared by reacting 2-hydroxy-3methoxy - propyl - mercaptan (from 1,2 - epoxy3-methoxy-propane and thioacetic acid, followed by hydrolysis with methanolic HCl) and 1,2 - epoxy - 3 - methoxy - propane to give 2,21 - bishydroxy - 3,31 - bismethoxy - propyl sulphide, oxidizing and ring closing this to give 3,5 - bismethoxy - methyl - 1,4 - thioxane - 1,1dioxide and reacting this with hydrazine hydrate. 1,2 - Epoxy - 3 - (21 - methoxyethoxy) - propane is prepared by reacting glycol monomethyl ether with epichlorhydrin. |
