Ketones derived from unsubstituted 2,3-dihydroperimidine were obtained by the selective reduction of the corresponding acylperimidines. The direct acylation of 2,3-dihydroperimidine in PPA is accompanied by dehydrogenation and leads to 4(9)-acylperimidines. The spectral characteristics of these products were discussed.
