Go around in (hetero)cycles! The palladium‐catalysed tandem cyclisation/coupling reaction of alkynyl‐ and alkenyl‐substituted aminomalonates leads to highly functionalised pyrrolidines and piperidines in good yield (see scheme). The reaction allows efficient access to a broad range of synthetically valuable building blocks.

The zinc(II)-catalyzed 5-exo-dig (Conia-ene) and 5-endo-dig cyclizations of a range of alkynyl-α-aminomalonates give rise to nitrogen heterocycles with good efficiency. The reaction allows the synthesis of a broad range of synthetically useful building blocks.
