β-unsaturated esters, α,β-unsaturated aldehydes and tri(n-butyl)stannyllithium, react with boron trifluoride etherate to produce vinyl cyclopropane carboxylic esters. An original highly convergent synthesis of chrysanthemic acid is reported.
容易得自α,β-不饱和酯,α,β-不饱和醛和三(正丁基)锡烷基锂的γ-羟基烯基锡烷与三氟化硼醚化物反应生成乙烯基环丙烷羧酸酯。据报道,菊花酸最初是高度收敛的合成。
