INTRODUCTION

The amide bond is one of the most commonly used chemical bonds in organic synthesis. The methods used to form this important functional group are often superchemically stoichiometric, leading to significant waste in the process. These factors led the American Chemical Society Green Chemistry Institute Pharmaceutical Roundtable (ACS-GCIPR) to highlight the catalytic synthesis of amide bonds as a significant initiative in green chemistry.1

REPRESENTATIVE TRANSFORMATIONS

In 2007, Milstein and his team described the dehydrogenative coupling of amines and alcohols to form amides, utilizing a ruthenium catalyst.3

Later, Madsen and his collaborators introduced an alternative catalyst system for this dehydrogenative coupling, significantly expanding its scope.4

In more recent developments, Hall and colleagues showcased boronic acid-catalyzed amidation reactions employing carboxylic acids as substrates.3
