Allgemeine Beschreibung

Product may polymerize over time during storage.

Anwendung

3-Oxetanone can be used to synthesize:

• Various oxetane-containing lead compounds with improved solubility, reduced lipophilicity and amphiphilicity.
• (Hydroxymethyl)oxazoles and (hydroxymethyl)thiazoles via single-step microwave mediated reaction with primary amides and thioamides, respectively.
• Oxetane containing spirocycles through thermal 1,3-dipolar cycloaddition reaction with α-amino acids or secondary α-amino acid esters.
