Asymmetric transfer hydrogenation of functionalized acetylenic ketones

A systematic study of the asymmetric transfer hydrogenations of functionalized acetylenic ketones and diketones has been completed, together with a total synthesis of (S,S)-(-)-yashabushidiol B. In several cases, excellent enantioselectivities and yields

Synthesis of the (4R,5R)-Isomer of 5-Hydroxy-6-phenyl-4-hexanolide, a Lateral Root-inducing Substance Isolated from Erwinia quercina

Lipase-catalyzed enantioselective lactonization of racemic methyl 6-phenyl-4-hydroxy-5-hexynoate worked well to afford (R)-6-phenyl-5-hexyn-4-olide (42 percent yield, 81 percent e.e.).The e.e. of the product was enhanced to 97 percent by the repetition of
