Synthesis of substituted pyridines and pyridazines via ring closing metathesis.
RCM can be used to make aromatic heterocycles, namely pyridines and, for the first time, pyridazines; the key step after RCM involves elimination of sulfinate to provide the aromatic system.
متن کاملMetal-free cyclotrimerization for the de novo synthesis of pyridines.
The de novo synthesis of pyridines from smaller molecules has attracted a lot of interest since pyridine is one of the most important heterocyclic structural motifs in numerous areas of organic chemistry. Many developed syntheses, such as the Kr hnke or the Hantzsch reaction, rely on condensation reactions of smaller molecules, but a number of synthetic approaches including cycloaddition reacti...
