Aldehydes were proved to be viable reagents for implementing alkenylation of α-oxoketenedithioacetals. AlCl3 was found to be the best catalyst. The established reaction opened an avenue to access densely substituted 1,3-butadiene derivatives. The obtained product bears multiple reactive sites that can be converted into various valuable molecules.

catalysis protocol for the synthesis of 4-(pyridin-2-ylmethyl)-2-aminopyrroles (PMAPs) was constructed by simply refluxing a mixture of ethyl 2-(pyridin-2-yl)acetates 1 and various types of arylglyoxal monohydrates 2 and different heterocyclic ketene aminals 3 in EtOH solvent. Based on this reaction, a series of highly functionalized PMAPs were obtained through a novel cascadereaction accompanied by a decarboxylation
