the Special Topic Modern Strategies for Heterocycles Synthesis Abstract A cationic palladium(II) complex catalyzed reductivecoupling of N-tosyl-tethered alkynones for the synthesis of functionalized piperidines was successfully developed. This reaction was initiated by hydropalladation of the alkyne and quenched by addition to the intramolecular carbonyl group. The substituent on the alkyne is key
