Thermal or Lewis acid-promoted electrocyclisation and hetero Diels-Alder cycloaddition of α,β-unsaturated (conjugated) carbodiimides: A facile synthesis of nitrogen-containing heterocycles

α,β-Diarylvinyl- and α-styryl-carbodiimides, prepared by the aza-Wittig reaction of iminophosphoranes with isocyanates, underwent either 6π-electrocyclisation upon heating or a Diels-Alder reaction under thermal or Lewis acid-promoted conditions with appr
