REACTION OF 2-ALKOXYCARBONYLMETHYL DERIVATIVES OF Δ2-OXAZOLINE Δ2-IMIDAZOLINE AND THEIR TAUTOMERS WITH 4-NITROBENZONITRILE N-OXIDE

Article abstract of DOI:10.1007/BF00474004

It was established that 2-alkoxycarbonylmethylene derivatives of oxazolidine and imidazolidine react readily with 4-nitrobenzonitrile N-oxide; the reaction takes place at the methylidyne carbon atom to give intermediate oximes, which can then undergo cycl
