摘要

通过串联 Knoevenagel-Michael 反应合成了融合的 2-氨基-3-氰基-4H-吡喃。在 2-氨基-3-氰基-4H-吡喃的开环过程中，发现了一种以前未知的 2,6-二氰基苯胺。通过 X 射线衍射确定了后一种化合物的结构。

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.
