Abstract
New 5,6-dihydro-1,3-thiazin-4-one derivatives have been synthesized by one-pot reaction of morpholin-4-amine and adamantan-1-amine with methacryloyl isothiocyanate. Structure of 5-methyl-2-(morpholin-4-ylamino)-5,6-dihydro-4 H -1,3-thiazin-4-one has been determined by X-ray analysis, and its high antiradical and anti-inflammatory activity has been revealed.
