SYNTHETIS OF CYCLIC AND ACYCLIC β,γ-UNSATURATED CARBOXYLIC ACIDS VIA AN E1-TYPE IONIZATION/ELIMINATION OF β-LACTONES

Black, T. Howard,Eisenbeis, Shane A.,McDermott, Todd S.,Maluleka, Stephen L.

, p. 2307 - 2316 (2007/10/02)

Cyclic and acyclic ketones were converted in three steps into 3-alkenoic acids, bearing a variety of substituents in the α-position.The sequence, involving ionization/elimination of a β-lactone, affords high yields of pure products uncontaminated with conjugated isomers.Support for an E1-type mechanism is also provided.
