A series of aldehydes carrying different functional groups was transformed directly into the α-methylene derivatives. Dialdehydes behaved comparably at both active sites. When keto aldehydes are involved, excellent levels of chemoselectivity are observed, with the ketone substructures exhibiting no sign of reactivity.
一系列带有不同官能团的醛被直接转化为δ-亚甲基衍
生物。二醛在两个活性位点的表现相当。当涉及酮醛时,可观察到极好的
化学选择性,而酮基结构则没有反应迹象。
