Condensation of 1,1-bisdialkylaminoethenes with aromatic aldehydes gives the corresponding trans-cinnamoyl amides in fair yield. Salicylaldehyde affords coumarin. 1,1-Bisdialkylamino-1,3-dienes and aromatic aldehydes produce 5-arylpenta-cis-2,trans-4-dienoyl dialkylamides. The mechanisms of these reactions have been explored. Some related condensations using 1-alkoxy-1-dialkylaminoethenes and 1-al
1,1-双二烷基氨基乙烯与芳族醛的缩合以适当的收率得到相应的反式肉桂酰基酰胺。水杨醛提供香豆素。1,1-双二烷基氨基-1,3-二烯和芳族醛产生5-芳基五-顺-2,反式-4-二壬基二烷基酰胺。已经研究了这些反应的机理。还研究了一些使用1-烷氧基-1-二烷基氨基乙烯和1-烷硫基-1-二烷基氨基乙烯的缩合反应。
