Abstract

Inventia se refera la un procedeu simplu, într-o singura etapa, de ciclocondensare MANNICH-WERNER pentru sinteza unor alpha-pirono-4-cromanone, pornind de la o orto-hidroxipropiofenona care poseda ciclu cumarinic. Inventia reprezinta o contributie la elucidarea generalizarii reactiei de ciclocondensare MANNICH-WERNER unor orto-hidroxicetone aromatice-alifatice substituite cu halogeni.
