Mt. Cocco et al., NEW TRIFLUOROMETHYLATED PYRIDINES FROM FUNCTIONALIZED N-1-ACYLACETAMIDRAZONES, Journal of heterocyclic chemistry, 33(6), 1996, pp. 1771-1773
Polyfunctionalized trifluoromethylpyridines 4, 5 were readily synthesi
zed from trifluoroacetylvinyl ether 3, using N-1-acylacetamidrazones 1
, 2 as starting material.
