Optically active (all-E,2R,2′R)-oscillol (= (all-E,2R,2′R)-3,4,3′,4′-tetradehydro-1,2,1′,2′-tetrahydro-ψ,ψ-carotene-1,2,1′,2′-tetrol; 1) was synthesized according to the C10 + C20 + C10 = C40 strategy, applying the Wittig reaction to couple the synthons 4 and 6. The chiral centre was introduced by a Sharpless dihydroxylation of 3-methylbut-2-enyl 4-nitrobenzoate (8).
光学活性的(清一色ë,2 - [R,2' - [R)-oscillol(=(清一色ë,2 - [R,2' - [R)-3,4,3',4'-四脱氢1,2,1',根据C 10 + C 20 + C 10 = C 40策略合成2'-tetrahydro-ψ,ψ-胡萝卜素-1,2,1',2'-tetrol; 1),采用Wittig反应偶联合成子4和6。通过3-甲基丁-2-烯基4-硝基苯甲酸酯的无尖锐的二羟基化作用引入手性中心(8)。
