Highly effective methods for introduction of several kinds of carbon substituents have been developed by means of organotin reagents. Allyl-, alkynyl-, allenyl-, and benzyltin reagents readily react with <I>N</I>-acylated nitrogen heteroaromatics and cyclic imines in a highly chemo- and regioselective manner. Functionalized acylating agents, such as α, β, γ, δ-unsaturated, α, β-unsaturated, and β-halogenated acyl chlorides can be utilized in the reactions and the subsequent intramolecular cyclizations afford nitrogen polycycles related to protoberberine, yohimbane, and indolizidine alkaloids.
