Indolizine Studies, Part 5: Indolizine-2-carboxamides as Potential HIV-1 Protease Inhibitors^[1]

Abstract

1,1-Carbonyldiimidazole-promoted coupling of Baylis–Hillman-derived indolizine-2-carboxylic acids with a range of amine and amino acid derivatives has provided access to the corresponding carboxamides in moderate to excellent yield.

Keywords:

• Baylis–Hillman reaction
• HIV-1 protease inhibitors
