Formation of Thietane Derivatives via Intramolecular (2+2) Cycloaddition On irradiation, the two 4‐vinyl‐1,3‐thiazole‐5(4 H )‐thiones 1a, b , synthesized from thiobenzoic acid and the corresponding 3‐amino‐2 H ‐azirines 2a , b , undergo an intramolecular (2+2)‐cycloaddition reaction of the CS and CC bonds to give the tricyclic thietane derivatives 3a , b .
