✦ Synopsis

1,2‐Epoxycarotenoids: Synthesis, ^1^H‐NMR and CD Studies of (S)‐1,2‐Epoxy‐1,2‐dihydrolycopene and (S)‐1′,2′‐Epoxy‐1′, 2′ ‐dihydro‐γ‐carotene

The synthesis of (S)‐1,2‐epoxy‐1,2‐dihydrolycopene (^(S)^‐1) and (S)‐1′, 2′ ‐epoxy‐ 1′, 2′ ‐dihydro‐γ‐carotene ((S)‐2) are described. The CD spectra of the (all‐E)‐isomers and of the isomers (7Z, S)‐1 and (7′Z, S)‐2 are discussed. The comparison of the CD spectra of the synthetic (S)‐1 and the compound isolated from the tomatoes proves the (S)‐configuration of the natural product.
