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.

Protein disulfide isomerase (PDI) regulates multiple protein functions by catalyzing the oxidation, reduction, and isomerization of disulfide bonds. The enzyme is considered a potential target for treating thrombosis. We previously developed a potent PDI inhibitor, CPD, which contains the propiolamide as a warhead targeting cysteine residue in PDI.

Nitric oxide (NO)-donor drugs, which stimulate reduced form of soluble guanylate cyclase (sGC), have different efficacy to the arteries and veins. This study examined whether sGC activators, which activate oxidized/apo sGC, also have arteriovenous selectivity similar to that of NO-donor drugs. The mechanical responses of the isolated blood vessels were assessed using the organ chamber technique and protein expression was verified using western blotting.

The introduction of multiple trifluoromethyl (CF) groups into aromatic compounds remains a significant challenge in synthetic chemistry. Here, we report an unprecedented visible light-promoted multiple trifluoromethylation of phenols using commercially available CFI. The key to success lies in our discovery of a "continuous activation strategy" that enables sequential trifluoromethylations through single-electron transfer from photoexcited phenoxide to CFI until all or positions are occupied.
