Photochemically generated ketyl and 2-dioxdanyl radicals are added with high diastereoselectivity (de > 95%) to (5R)-(-)-5-menthyloxy-2[5H]furanone. This reaction is used for the asymmetric synthesis of (-)-terebic acid. The double bond is attacked by the radicals on the ul-side.

activities and stereoselectivities and lactone products were obtained in moderate to excellent yields; importantly, enzyme‐based stereocontrol allowed access to both enantiomers in up to >99% ee. Chiral recognition of a distant γ‐center led to kinetic resolution with remarkable enantioselectivities (E values up to 49). An unprecedented case of dynamic kinetic resolution was observed with 3‐methyl‐5‐phenylfuran‐2(5H)‐one
