Green Synthesis of a Novel Functionalized Tetrahydro-1,4-thiazepine and Computational Studies of Its Tautomeric Structures
摘要:
Reaction of ethyl-2-cyano-3,3-dimercaptoacrylate dipotassium salt with 2-chloroethylamine hydrochloride in water afforded the novel (4E,6E)-ethyl 5-amino-2,3-dihydro-7-mercapto-1,4-thiazepine-6-carboxylate. The molecular geometry of the most stable tautomeric structure was investigated with DFT and AIM at the B3LYP level of theory using the 6-31G** and 6-311+G** basis sets.
