conjugated dienones 1a, 1c−e, and 1g were synthesized by aldol reaction of cyclohex-2-enones 3 with aldehydes or ketones and subsequent elimination. Whereas the acetone adducts could be converted into the desired products 1a/g by treatment with CeCl3·7H2O/NaI, the dienones 1c−e were obtained by Appel bromination and dehydrobromination with triethylamine.

共轭二烯酮 1a、1c-e 和 1g 是通过环己-2-烯酮 3 与醛或酮的羟醛反应和随后的消除合成的。而丙酮加合物可以通过用 CeCl3·7H2O/NaI 处理转化为所需的产物 1a/g,而二烯酮 1c-e 是通过 Appel 溴化和用三乙胺脱溴化氢得到的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
