Abstract
A novel method has been developed for the synthesis of 1,3-thiazin-4-one compounds containing trifluoromethyl groups utilizing 2-trifluoromethyl acrylic acid and thioamides as key starting materials. This protocol is characterized by its simplicity, practicality, and tolerance toward various functional groups. Given the straightforward nature of the procedure, the ready availability of both starting materials, and the significance of drugs containing trifluoromethyl, it is anticipated that this reaction will have wide-ranging applications.

Abstract
A formal [4 + 2]-cycloaddition reaction of N-alkoxy acrylamides and acyl isothiocyanates was developed via a Lewis base-catalyzed cascade aza-nucleophilic addition/thio-Michael addition process under mild conditions. This study provides a facile approach for preparing 2-imino-1,3-thiazinone derivatives in moderate to excellent yields and enriches the field of heterocyclic acrylamide chemistry. The reported method features metal-free reaction conditions, high atom economy, and easy operation. Moreover, the reaction was successfully scaled up and derivatization reactions were successfully performed.

Abstract
3,4-Dihydro-2H,6H-pyrimido[1,2-c][1,3]benzothiazin-6-imine (PD 404182) and 3,4-dihydro-2H-benzo[4,5]isothiazolo[2,3-a]pyrimidine are the heterocyclic antiretroviral agents against human immunodeficiency virus type 1 (HIV-1) infection. On the basis of similar structure-activity relationships of anti-HIV activities toward the early-stage of viral infection between these unique scaffolds, the transformations under the bioassay conditions were investigated. The distinctive S-N bond in the isothiazolopyrimidine scaffold was immediately cleaved under reductive conditions in the presence of GSH to generate a thiophenol derivative. A similar rapid conversion of PD 404182 into the same thiophenol derivative was observed, suggesting that pyrimidobenzothiazine and isothiazolopyrimidine scaffolds may work as prodrug forms of the common bioactive thiophenol derivatives.
