A stereoselective one-pot transformation of simple enol-lactone
derivatives into the corresponding more complex compounds having the
bicyclo[m.n.1] ring system was investigated. Under
improved reduction conditions using DIBAL-H, the enol-lactones
efficiently provided the bicyclo[m.n.1] derivatives
via tandem reduction of the lactone moiety, aldol reaction and
subsequent reduction of the resulting carbonyl functionality.
研究人员研究了将简单的烯醇内酯类衍生物通过立体选择性的一锅法转化为具有双环[m.n.1]环系统的相应更复杂化合物的过程。在DIBAL-H的改善还原条件下,烯醇内酯类衍生物通过串联还原内酯部分、缩醛反应和随后还原生成的羰基官能团,有效地提供了双环[m.n.1]衍生物。
