Transformation of γ-ketoaldehyde acetals into 3-substituted-2-cyclopentenones via cyanophosphates under mild conditions
The reaction of cyanophosphates, which are readily derived from γ-ketoaldehyde acetals, with TMSN3 (3 eq)/Bu2SnO (0.3 eq) in refluxing toluene directly furnished 3-substituted-2-cyclopentenones in modest to good yield under mild conditions. The present method was further applied toward the synthesis of dechlorotrichodenone C isolated from Trichoderma asperellum.
氰基磷酸酯很容易衍生自γ-酮醛缩醛,它与TMSN 3(3 eq)/ Bu 2 SnO(0.3 eq)在回流的甲苯中反应,在温和的条件下以适度到良好的收率直接提供了3-取代的2-环戊烯酮。本发明的方法进一步应用于从曲霉木霉分离的脱氯麦草酮C的合成。
