日期:1988.1
Bridged thiazoliumsalts (6a,b) have been synthesized using macrolactonisation techniques to make the corresponding thiazolinethiones (4a,b) followed by treatment with H2O2. For each compound the bridge exists predominantly in a single conformation which has been determined both by n.m.r. and X-ray crystallography.
已使用大环内酯化技术合成了桥接的噻唑鎓盐(6a,b),以制备相应的噻唑啉硫酮(4a,b),然后用H 2 O 2处理。对于每种化合物,桥主要存在于单一构象中,该构象已通过nmr和X射线晶体学确定。

The reactivity of bridgedthiazoliumsalts (9) and (10) has been studied; the model (9) with the shorter bridge is unable to catalyse the benzoin condensation reaction and it was shown that this is due to failure of the condensation step (5)→(6), probably owing to the effects of strain.
