out with isoprene epoxide (ZnCl2 /MeNO2 ) leading directly to α-cis 10 a, α-trans 10b and γ 10c hydroxyprenylionones. The α-cis and γ-isomers have been converted in few steps into the C50 carotenoids decaprenoxanthin 1 and C.p. 450 3 respectively.
已用异戊二烯环氧化物(ZnCl 2 / MeNO 2)进行了假紫罗兰酮4的远端双键的烷基化,直接导致α-顺式10a,α-反式10b和γ10c羟基异戊二烯酮。α-顺式和γ-异构体仅需几个步骤即可分别转化为C 50类胡萝卜素癸酸黄嘌呤1和Cp 450 3。
