Dioxopyrrolines. XLII. Mechanism of 7-Epimerization Reaction of 7-Substituted 5-Ethoxycarbonyl-1-phenyl-2-azabicycloheptane-3,4-diones

7-Mono- and 7,7-disubstituted 5-ethoxycarbonyl-1-phenyl-2-azabicycloheptane-3,4-diones undergo epimerization at C-7 when treated with base.Experiments using the stereospecifically deuterium labeled compound 6 showed that the inversion of stereochem

2-AZABICYCLOHEPTANE-3,4-DIONES (3): LEWIS ACID CATALYSED RING EXPANSION OF 3-ETHOXY-Δ2-AZABICYCLOHEPTAN-4-ONES: SYNTHESIS OF 2-ETHOXY-3-AZATROPONES

Treatment of 2-azabicycloheptane-3,4-dione imidic ester (6) with tin(IV) chloride gave the dihydroazatropolone 2-ethyl ethers (7) in moderate yields which were also obtained by reaction of dihydroazatropolones (2) with Meerwein reagent.DDQ oxidation of 7 gave 2-ethoxy-3-azatropones (8), which rearranged, on treatment with water, into ethyl pyridine 2-carboxylate (10).Spectroscopic data of azatropolone 2-ethyl ethers were also described.
