A chemoselective strategy toward a variety of fused heterocyclic scaffolds relying on a three-component condensation of heterocyclic ketene aminals (HKAs) or corresponding thioaminals with aryl glyoxals and cyclic 1,3-dicarbonyl compounds has been developed and explored. Depending on the applied combination of substrates, the strategy can be tuned to provide straightforward access to imidazo[1,2-a]quinoline
已经开发和探索了一种针对各种稠合杂环支架的化学选择性策略,该策略依赖于杂环烯酮缩醛胺(HKA)或相应的硫代缩醛胺与芳基乙二醛和环状1,3-二羰基化合物的三组分缩合。根据所应用的底物组合,可以调整策略以直接获取咪唑并[1,2- a ]喹啉、吡咯并[1,2- a ]咪唑和吡咯并[2,1- b ]噻唑骨架。

Treatment of all-trans-retinal with a series of 1,3-diketones using Knoevenagel conditions gave the expected condensation products. These retinylidene 1,3-diketones were characterized and their biological activities in the hamster tracheal organ culture test measured. It was found that the cyclohexane- 1,3-dione derivatives are highly active in this in vitro assay, while other 1,3-diketones are less active. Retinylidenedimedone has been chosen for further evaluation.
