Abstract :
The results of asymmetric hydrogenation of diethyl 3,4-dioxohexanedioate are presented. (R,R)-1,5-Dioxa-2,6-dioxobicyclo[3.3.0]octane, the product of hydrogenation and subsequent cyclization, was obtained in high enantiomeric excess. This compound was transformed into synthetically useful (R)-4-hydroxyethyl-2-buten-4-olide.
