A convenient one-step synthesis of chiral γ-lactones has been performed. The method is based on enantioselective hydrogenation of γ-ketoesters using the RuCl3-BINAP-HCl catalytic system. Chiral γ-lactones (91-99% ee) have been isolated in 57-88% yield.

Ketones can be generated from secondary alcohols by converting the latter into quinaldine ethers followed by irradiation (>320 nm).The quinaldine ethers can therefore be utilized as latent carbonyl groups.The quinaldine group is chemically inert during transformations at other parts of the molecule involving hydroboration, Grignard reagents, LiAlH4, as well as bromine or ozone. Key Words: Ketone formation, photochemical; Protecting group
