The results showed that H of HEH and N-Me-HEH was transferred to the α-position of FDCN to form the thermodynamically unfavorable 9- fluorenide carbanion, respectively, while D of the 4, 4-deuterated derivatives of HEH and N-Me-HEH was transferred to the 9-position of FDCN to form 9-fluorenylmalononitrile carbanion.

而模型化合物4—位氘代物上的D则转移到FDCN的9—位，形成了9—芴基丙二腈碳负离子。

One-pot three component condensation reactions of aromatic aldehydes, malononitrile, and barbituric acid were described for the preparation of a series of pyrano[2,3-d]pyrimidine derivatives under ultrasonic irradiation in aqueous media without catalyst.

报道了在超声波辐射下，水相中无催化剂下通过芳香醛与丙二腈、巴比妥酸的一锅反应，合成了一系列吡喃并[2，3-d]嘧啶衍生物。
