How medicinal chemistry triggers fundamental research in heterocyclic chemistry. The chemistry of 4-hydroxy-2-pyrones and a new imidazole antifungal agent.

The results herein described point out that the efforts devoted to the preparation of significant molecules can not be separated from those devoted to the discovery of new synthetic methodologies and to the solution of fundamental chemical problems. The border between basic and applied research vanishes very frequently.
