A number of 2-aminoethanethiol derivatives, RNH (CH&SY, in which R is an alicyclic or heteroalicyclic group and SY is a suitable S function (eg, thiol, thiosulfate, or phosphorothioate), were synthesized for evaluation as antiradiation agents. The intermediate N-substituted 2-bromoethylamines were prepared from either 3-substituted 2- oxazolidinones derived from primary amines or N-substituted 2-aminoethanols derived ...
