Multicomponent synthesis of highly substituted 2-pyridones
A novel synthesis of polyfunctionalised pyridones, structurally related to cardiotonic agent milrinone is described. The procedure consists of an Ugi four-component reaction of 3-formylchromones, followed by a base-promoted ring-opening/ring-closing proce
