Synthesis of Optically Active 1,4-Thiazane-3-carboxylic Acid<i>via</i>Optical Resolution by Preferential Crystallization of (<i>RS</i>)-2-Amino-3-[(2-chloroethyl)sulfanyl]propanoic Acid Hydrochloride
Optically active 1,4-thiazane-3-carboxylic acid [TCA] was synthesized from cysteine via opticalresolution by preferentialcrystallization. The intermediate (RS)-2-amino-3-[(2-chloroethyl)sulfanyl]propanoic acid hydrochlo-ride [(RS)-ACS•HCl] was found to exist as a conglomerate based on its melting point, solubility and IR spectrum. (RS)-ACS•HCl was optically resolved by preferential crystallization
