摘要:
Stereoisomeric Sinensiaxanthins and Sinensiachromes: Separation and Absolute ConfigurationThe so‐called sinensiaxanthins and sinensiachromes, important apocarotenols from various fruits, have been separated into 2 and 4 stereoisomers, respectively, and their absolute configurations have been determined: (3S,5R,6S)‐5,6‐epoxy‐5,6‐dihydro‐10′‐apo‐β‐carotene‐3,10′‐diol (2), its (9Z)‐stereoisomer 7, the (8R)‐ and (8S)‐epimers of (3S, 5R)‐5,8‐epoxy‐5,8‐dihydro‐ 10′ ‐apo‐β‐carotene‐3, 10′‐diol (4and5), and their (9Z)‐stereoisomers3and probably6.Thus, sinensiaxanthins are cleavage products from (Z/E)‐isomeric antheraxanthins or violaxanthins (scission at C(9′)–C(10′))
