A general synthetic approach has been developed for the first asymmetric total synthesis of tuberolactone 1, jasmine lactone 2 and δ-decalactone 3. The key step is the selective hydrogenation of triple and endocyclic double bonds in the key intermediate 4.

Optical resolution of six chiral fragrant lactones (δ-jasmine lactone, massoia lactone, tuberolactone, pentynyllactone, δ-decalactone, and γ- nonalactone) was investigated by means of either the diastereomeric salt formation method or the diastereomeric amide formation method. Using these procedures, we obtained each enantiomer from five of the six lactones, except for massoia lactone. All five lactones were obtained in a good yield and with high optical purity. Sensoric characteristics on both enantiomers and racemic modification of four lactones are given.

(-)-(2S)-Ethyl 2-hydroxyhexanedioate ((2S)-2) was obtained by kinetic resolution of racemic ethyl 2-hydroxyhexanedioate with baker's yeast.The key intermediates (+)-(5R)- and (-)-(5S)-ethyl 5,6-epoxyhexanoate ((5R)- and (5S)-6, resp.) are proved to be use
