six-step synthesis of xanthohumol (1a) and its d3-derivative (1b) from easily accessible naringenin is reported. The prenyl side chain was introduced by Mitsunobu reaction followed by the europium-catalyzed Claisen rearrangement and base-mediated opening of chromanone gave access to an α,β-conjugated ketone system. Compound 1b was used as an internal standard in stable isotope dilution assays of 1a in
报道了从容易获得的柚皮素中六步合成黄腐酚 ( 1a ) 及其 d 3 -衍生物 ( 1b )。通过 Mitsunobu 反应引入异戊二烯侧链,随后铕催化的 Claisen 重排和碱基介导的色原酮打开得到 α,β-共轭酮系统。化合物1b用作两种波兰啤酒中1a的稳定同位素稀释测定的内标。
