title: Recent developments in utility of green multi-component reactions for the efficient synthesis of polysubstituted pyrans, thiopyrans, pyridines, and pyrazoles.
abstract: Developments made since 2010 in the utilization of multi-component reactions as green efficient methodologies for the synthesis of polysubstituted pyrans, thiopyrans, pyridines, and pyrazoles are reviewed and the mechanisms of these processes are discussed. Reference is made to classical older synthetic methods developed earlier in our laboratories.
