Condensation of oxazoles with dienophiles
Tetrahedron, 1969Abstract Pyridoxine analogues have been synthesized via a Diels—Alder reaction of 5-ethoxyoxazoles with dimethyl maleate followed by reduction. The products on oxidation with manganese dioxide yielded pyridoxal analogues. Pyridoxamine derivatives were obtained by reduction of the pyridoxal oximes. Phosphorylation of the pyridoxamine analogues and the

An expedient strategy for the synthesis of 5-oxazole ketones was developed via homogeneous gold catalysis with 4-MeO-TEMPO as an oxidant. The desired 5-oxazole ketones were achieved in decent yields with an excellent functional group compatibility under ...

AbstractThe reaction of 2‐propargyloxybenzamide with strong base has been shown to lead to formation of an oxazole and not a benzoxazepinone as reported. The structure has been confirmed by synthesis.
