Abstract

Monoacylated symmetrical secondary diamines are building blocks1 or intermediates2 widely used in the drug discovery process that are present in several investigational and established drugs. 3 Examples include the cardiotonic agent vesnarinone and the antihypertensive agent prazosin (Chart 1). Direct monoacylation of symmetrical diamines is frequently fraught with the complication associated with the tendency for bis-acylation to ...
