Abstract
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-alkylthio-1-dialkylaminoethenes have also been examined.Keywords
