An unprecedented formation of 11H-benzo[5,6][1,4]thiazino[3,4-a]isoindol-11-ones I (R1 = 2-Me, 2-MeO, 2-F, 3-F; R2 = H, Me, OMe, Cl, Br) through a one-step reaction of differently substituted 2-aminobenzenethiols 2-H2N-5-R2C6H4SH and 2-bromo-(2/3-substituted phenyl)-1H-indene-1,3(2H)-diones II in freshly dried ethanol under reflux conditions has been investigated. This unique transformation probably occurs through an initial nucleophilic substitution followed by ring opening and subsequent intramol. cyclization. The structures of all the synthesized benzo[1,4]thiazino isoindolinones I were established by FTIR, 1H NMR, 13C NMR, HRMS, and X-ray crystallog. anal. This approach was found to be simple and convenient and provides several advantages such as substantial atom economy, short reaction time and operational simplicity.
