In this study, enamines of cyclic ketones reacting with methyl acetylenecarboxylate to produce intermadiate cyclobutene adducts have been isolated. Reactions of methyl acetylenecarboxylate with enamines derived from cyclobutene adducts and ring expan

Anhydrous Ce(SO4)2 in chloroform selectively converts oximes into the parent carbonyl compounds in good yields. Hammett correlations helped to indicate a plausible mechanism for the above reaction. The formation of 1-(dinitromethyl)benzene was assume

Imidazolin-3-oxides 1 were reduced with NaBH 4 in THF at reflux to give the corresponding 2,3,5-triarylimidazolidin-1-oles 2 , which are proved to be in a ring–chain–ring tautomeric equilibrium with N -2-aminoethyl nitrones 3 and 3,5,6-triphenyl-
