Eco-friendly synthesis of novel thiohydantoin-type sulfur-containing imidazolinone derivatives from glycine ester

, 2018
Imino derivatives of glycine ester were prepared from methyl glycinate by the known procedure and then they reacted with several amines under microwave irradiation without solvent that gave the corresponding glycine amides.
