## Bridged thiazolium salts (6a,b) have been synthesized using macrolactonisation techniques to make the corresponding thiazolinethiones (4a,b) followed by treatment with H202. For each compound the bridge exists predominantly in a single conformation which has been determined both by n.m.r. and X-r
] n 1 has been synthesized and structurally characterized. Compound 1 is monoclinic, P2 1 / c with unit cell parameters a = 8.8759(9) ร , b = 11.4112(11) ร , c = 8.8908(9) ร , b = 106.010(6)ยฐ, V = 865.6(1) ร 3 , Z = 2 and D calc. = 1.600 g cm ร3 . The structure refined to R 1 = 0.0245, wR 2 = 0.0626 fo
