Effective Strategy

An effective strategy for the stereoselective synthesis of spiro isoxazolone-cyclohexenimines was developed by bifunctional squaramide–catalysed vinylogous Michael addition/cyclization cascade reaction of 4-unsaturated isoxazol-5-ones and α,α-dicyanoalkenes. The atom-economical cascade process can...
