The Stevens 3,2 rearrangement of dialkylammonium salts containing, along with 4-penten-2-ynyl, an alkoxycarbonylmethyl group, gives mostly hydrogenated products, with simultaneous dealkylation and aldehyde formation. On acid treatment enamine amino esters give keto esters or their further transformation product, 4-ethyl3-hydroxy-5-methyltetrahydrofuran-2-one.
