摘要：

2-Acyl-3,4-dimethylthiazolium triflates, modelled upon the biologically important 2-acyl thiamine derivatives, react in neutral media specifically with the oxygen atom of N-aryl hydroxylamines to give rise to tetrahedral intermediates, which collapse to the O-acyl derivatives under mildly basic conditions.
