Abstract

Attempts to obtain iminothio esters and dithio esters from α-aminoacetonitrile gave stable products only with the amino group acylated by the carbobenzoxy function. An iminothio ester derived from β-aminopropionitrile was found to be relatively stable as the dihydrochloride, however. Examples of both α- and β-cyanoalkylthio-sulfates were found to be stable as the sodium salts. Antiradiation testing of the β-amino iminothio ester dihydrochloride and the α-cyanothiosulfate showed no protective properties.
