- Abstract
The reactivity of Mannich bases derived from 6- and 7-hydroxycoumarins was studied in inverse electron demand Diels-Alder reactions with enamines. The reactions were shown to proceed by a cycloaddition mechanism followed by transformation of hemiaminals and resulted in the formation of heterocyclic pyrano[2,3- a]xanthene, pyrano[2,3- b]xanthene, and pyrano[3,2- b]xanthene.
