An Ugi–Joullié Platform for Medicinally Relevant 1,4‐Dihydrobenzothiazines [PDF]

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
A series of benzothiazine derivatives was efficiently synthesized via an UJ‐2CR of a preformed imine and diverse isocyanides. The method features mild, room‐temperature conditions, broad functional‐group tolerance, and scalability, enabling rapid access to a chemically diverse library of 19 adducts with potential for further medicinal chemistry ...

thiazines [PDF]

ChemMedChem, 2022
8‐Nitro‐4H‐benzo[e][1,3]thiazinones (BTZs) are potent in vitro antimycobacterial agents. New chemical transformations, viz. dearomatization and decarbonylation, of two BTZs and their influence on the compounds’ antimycobacterial properties are described.
