Synthesis, molecular and crystal structure of 2-[2-(2-amino-3-cyano-4H-chromen-4-yl)-cyclohexylidene]malononitrile
摘要:
Condensation of salicylaldehyde with cyclohexylidenemalononitrile and hydrazine hydrate results in 2-[2-(2-amino-3-cyano-4H-chromen-4-yl)cyclohexylidene]malononitrile, the structure of which was studied by XRD.

A one-pot synthesis of 2-amino-4H-chromenes was achieved in good yields from three-component reaction of salicylaldehyde, malononitrile, and α,α-dicyanoalkenes catalysed by triethylamine.
