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.
