A. Alberola et al., THE REACTIONS OF 5-ARYL-2,3-DIMETHYLISOXAZOLIUM SALTS WITH AROMATIC-ALDEHYDES, Journal of heterocyclic chemistry, 30(2), 1993, pp. 461-465
The reactions of the 3-methyl group in 5-aryl-2,3-dimethylisoxazolium
tetrafluoroborates with aromatic aldehydes, in the presence of piperid
ine were studied. Isoxazolium salt reactivity is independent of the ph
enyl group substituent at C-5 on the isoxazolium salt ring. However, i
t does depend on the aldehyde structure.
