An efficient method for the preparation of a variety of 2-aminomethyl-1,3-dienes was developed through the reaction of imines with 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.

3-triazole and isoxazole scaffolds has been prepared. The protocol utilized alkynyl substituted amines as the bifunctional linkers to combine a copper-free triazole synthesis with a hypervalent iodine-mediated isoxazole cycloaddition through a chemoselective process. This method has also been exemplified in the construction of bisfunctional-modified peptidomimetics by combining three reactions in a sequential

demonstrates the first zeolite‐catalyzed synthesis of piperidine derivatives, including peptidomimetics and indoloquinolizidine alkaloids. The approach developed utilizes a highly effective one‐pot reaction cascade, through imine formation and imino‐Diels–Alderreactions, promoted by scandium‐loaded zeolites as a heterogeneouscatalyst. The methodology described benefits from very low catalyst loadings (≤5 mol %
