Three-component synthesis of 2-amino-3-cyano-4H-pyrans and a new version of the pyran ring opening

Fused 2-amino-3-cyano-4H-pyrans were synthesized by the tandem Knoevenagel—Michael reaction. A previously unknown version of the ring opening of 2-amino-3-cyano-4H-pyrans giving substituted 2,6-dicyanoaniline was discovered. The structure of the latter compound was established by X-ray diffraction. © Springer Science+Business Media LLC 2024.
