2-aryl-4-hydroxy-5-thio substituted 1,3-thiazin-6-ones were synthesized for human immunodeficiency virus-1 protease inhibition. These compounds were synthesized by the treatment of 4-hydroxy-5-thio substituted-1,3-thiazin-6-ones with the corresponding sulfenylchlorides. The products were obtained in good isolated yields, inspite of the presence of bulkyl substitutents at the ortho position of phenyl sulfenyl chloride

A new and efficient route for the synthesis of derivatives of the poorly investigated pyrano[2,3‐d][1,3]thiazine heterocyclic system is disclosed. These compounds were prepared via annulation of 2‐aryl‐4‐hydroxy‐6H‐1,3‐thiazine‐6‐ones with aliphatic and aromatic aldehydes in the presence of pyridine. The method is general and versatile, and the interaction is independent on the nature of the aldehyde
公开了一种新的有效途径,用于合成研究较少的吡喃并[2,3- d ] [1,3]噻嗪杂环系统的衍生物。这些化合物是通过在吡啶存在下,将2-芳基-4-羟基-6 H -1,3-噻嗪-6-与脂肪族和芳香族醛环合制得的。该方法是通用且通用的,并且相互作用与醛的性质无关,唯一的例外是甲醛和水杨醛。
