Synthesis of 1,3-dienes
An efficient method for the preparation of various 2-aminomethyl-1,3-dienes was developed through the reaction of imines with an organoindium reagent generated in situ from indium and 1,3-dibromo-2-butyne. Three-component reactions of aldehydes, amines, and organoindium reagents gave successful results in a one-pot process.
