A general and efficient protocol was developed for the synthesis of polysubstituted pyridines from propargyl amines and unsaturated carbonyl compounds through a tandem condensation/alkyne isomerization/6π 3‐azatriene electrocyclization sequence. This process was found to be applicable to a wide range of readily available substrates (30 examples, up to 95 % yield) and could be readily performed on a

different methodologies have been developed for the synthesis of these kinds of molecules. However, a sustainable and efficient procedure for the synthesis of pyridines is still highly desirable. In this Synpacts article, we highlight our recent approach to the construction of highly substituted pyridines though a tandem condensation/alkyne isomerization/6π-3-azatriene electrocyclization sequence.
