Synthesis of morpholine derivatives and Bunte's salt as compounds of potential radioprotective activity

The purpose of the present study was to obtain several compounds possessing radioprotective activity. The syntheses yielded seven undescribed compounds i.e.: benzyl ester of the N-morpholinecarbathionothioglicol acid, ester bis S-(morpholine-4-thiocarbonyl)-2-thioethyl, morpholine salt of the N-morpholinecarbothionothiolic acid, sodium and potassium salt of S-morpholine-4-carbonyl, methylthiosulfate, sodium and potassium salt of beta-hydroxyethyl thiosulfate. Moreover, with the aid of other methods following compounds were synthetized: beta-S-(morpholine-4-thiocarbonyl) ethyl thiopropioniane, amide of the S-(morpholine-4-thiocarbonyl)-thioglicol acid, acid S-(morpholine-4-thiocarbonyl)-thioglicol acid, sodium salt of the S-(morpholine-4-thiocarbonyl)-thioglicol acid. The structure of these compounds was confirmed using elementary and spectral analysis. (author)
