A facile one-pot synthesis and heterocyclisation of (R)-2-amino-3- ((aroylcarbamothioyl)thio)propanoic acids

Mohebat, Razieh,Kafrizi, Elahe

, p. 172 - 174 (2014/04/17)

A series of (R)-2-amino-3-((aroylcarbamothioyl)thio)propanoic acid derivatives have been synthesised by a one-pot, threecomponent reaction of L-cysteine with ammonium thiocyanate in the presence of various acid chlorides under solvent-free conditions in excellent yields. These compounds were converted to (R)-2-thioxothiazolidine-4-carboxylic acid in water under reflux conditions.
