Overview

Substituted 1-pyrazolo[3,4-]pyridine-4- and 1-pyrazolo[3,4-]pyridine-6-carboxamides have been synthetized through a Doebner-Ugi multicomponent reaction sequence in a convergent and versatile manner using diversity generation strategies: combination of two multicomponent reactions and conditions-based divergence strategy. The target products contain as pharmacophores pyrazolopyridine and peptidomimetic moieties with four points of diversity introduced from readily available starting materials including scaffold diversity. A small focused compound library of 23 Ugi products was created and screened for antibacterial activity.
Ugi bisamides based on pyrrolyl-β-chlorovinylaldehyde and their unusual transformations.
