Popis:	The synthesis of cyclic imines 2, β-enaminones 6, and β-enaminodiketones 7 is described. Regio- and stereospecific thermolysis of β-enaminoesters 4 with boric acid permit these preparations in generally good yields.Key words: boric acid, cyclic β-enaminoesters, decarboxylation, cyclic imines, cyclic β-enaminones.
