Реакции

The reaction of ethyl 2-oxo cyclohexane carboxylate (I) with phenyl vinyl sulphoxide (II) and sodium hydride followed by pyrolysis of the resulting phenyl sulphonyl ethyl compound (III) gives the 1-vinyl compound (IV).
Baeyer-Villiger oxidation of methyl 3- and 4-oxocyclohexanecarboxylates gave the expected hexanolides, whereas ethyl 2-oxocyclohexanecarboxylate(I) gave 5-ethoxyoxalylpentanoic acid by way of ethyl 1-hydroxy-2-oxocyclohexanecarboxylate, formed by epoxidation of the enol form of (I)[1-2].
