It also concerns phytosanitary formulations or resin-solubilising formulations comprising at least one such furfural derivative of formula (I).
Durch basekatalysierte Reaktion zwischen aromatischen Aldehyden und 3‐Methyl‐2‐butanon in wäßrig‐ethanolischer Lösung bei 70° konnten die 5‐Aryl‐3‐isopropyl‐6,6‐dimethyl‐2‐cyclohexenone 4a‐f dargestellt werden. Benzaldehyd und Butanon reagierten analog; zwei der vier möglichen, in schlechter Ausbeute anfallenden 5‐Aryl‐2‐cyclohexenone 6 waren als Oxime zu isolieren.

The present invention relates to novel dihydropyrones with tethered heterocycles having improved pharmacologic properties which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The dihydropyrones are useful in the development of therapies for the treatment of viral infections and diseases including AIDS. The present invention is also directed to methods of synthesis of the dihydropyrones and intermediates useful in the preparation of the final compounds.
