Suitably functionalized glycine derivatives undergo a cross‐enyne and ring‐closing metathesis cascade to generate macroheterocyclic ring systems in good yield. These macrocycles, prepared on the basis of a fragment coupling strategy, consist of 13–16‐membered rings. To this end, 1,5‐hexadiene was found to be a promising cross‐coupling partner to generate macrocycles by this tandem metathesis sequence.(© Wiley‐VCH Verlag GmbH & Co.
