induction, and catalyst load in comparison to other procedures. The developed methodology was applied in the enantioselective synthesis of (5R,6S)‐(+)‐pteroenone, a defensive metabolite (ichthyodeterrent) of the Antarctic pteropod Clione antarctica.
烯丙基化,反式-和顺式-(2 crotylation ë,4 ê)-2,4- dimethylhexadienal,代表性α,β,γ,δ不饱和醛,在不同的催化和化学计量的条件下进行。与其他方法相比,有机催化剂TRIP-PA和N,N'-二氧化物催化的反应在收率,不对称诱导和催化剂负载方面提供了最佳结果。所开发的方法应用于(5 R,6 S)-(+)-戊烯酮的对映选择性合成,这是一种南极翼足类Clione南极的防御性代谢产物(鱼类去甲脂)。
