Heterocyclic Chemistry – A Mature Area in Its Infancy!

For a long time, the construction of heterocycles reliably forged a carbonheteroatom bond by the interaction between a nucleophilic heteroatom and an electrophilic C=X or C–X‐moiety. This concept has been greatly expanded with the development of many synthetic methods that seemingly defy standard reactivities in molecules. The collection of almost 100 articles in the special issues of Eur. J. Org. Chem. and Asian Org. Chem. impressively attest to the creativity and efforts that are going on in this field: mature, but still young at heart.
