  Reaction of aminals of conjugated unsaturated ?-dimethylaminoaldehydes with 1,2-, 1,3-, 1,4-, 1,5-, and 1,6-diketones

  摘要：

  The condensation of aminals of beta-dimethylaminoacrolein and 5-dimethylaminopenta-2,4-dienal with cyclic and acyclic 1,2-, 1,3-, 1,4-, 1,5-, and 1,6-diketones was studied. A series of previously unknown bis(omega,omega'-dimethylaminopolyenyl)diketones was synthesized; their structures were established by means of H-1 and C-13 NMR spectroscopies. The electron absorption spectra were employed to study the mutual influence of omega-aminopolyene chromophores separated by two C=O groups.
