A tandem reaction involving cross metathesis followed by concomitant cyclisation has been developed for the synthesis of substituted pyrroles. Various protected electron-deficient N-allylamines reacted with α,β-unsaturated carbonyl compounds in the presence of Lewis acids under the cross metathesis conditions using selected Ru olefin metathesis catalysts in order to form pyrroles.
