Abstract

1. It has been shown that, depending on structure, secondary amines react with tertbutyipropynal at the C≡C or C=O bonds to form acetylenic aminals or Michael adducts. 2. Acyclic and aromatic secondary amines add to tert-butylpropynal only at the triple bond. Dialkylamines with bulky substituants (i-Pr, n-Bu) add to both the β- and α-positions of the acetylenic fragment. 3. β-Aminoacroleins, containing tertiary and secondary amino groups, spontaneously isomerize to enaminoketones.
