A multicomponent cascade reaction for the synthesis of novel chromenopyranpyrazole scaffolds
Chem Commun (Camb).
.
Abstract
A catalyst, solvent, work-up and column free synthesis of chromenopyranpyrazoles via multicomponent cascade reaction has been achieved with high stereoselectivity. This novel reaction creates two N-C, two C-C and one O-C bonds through a domino process for the construction of three new rings and three contiguous stereogenic centers.
