Am. Magerramov et al., New synthesis of tetrahydro-1,4-thiazine-3-ones from 1,2-aminopropanethiols and alpha-chlorocarboxylic acids, SYN COMMUN, 29(4), 1999, pp. 721-728
Tetrahydro-1,4-thiazine-3-ones 5 can be efficiently prepared by the condens
ation of 1,2-aminopropanethiols 1 and sodium chlorocarboxylates 4 under bas
ic conditions.
