Regioselective, uncatalyzed additions of alcohols and carboxylic acids to 2-furyloxirane. Synthetic applications.
摘要:
Nucleophilic non-catalyzed additions of alcohols and carboxylic acids to 2-furyloxirane are reported. The intramolecular Diels-Alder reactions of one addition product are also described.
Lewis acid mediated one-pot transformation of D-glucal in the presence of nucleophiles leads to the formation of racemic alpha-substituted alpha-hydroxymethyl furfuryl derivatives, versatile synthons for biologically active molecules. Transformations using O-, S-, C-, and N-nucleophiles could be achieved readily under mild and scalable conditions. Indium triflate proved to be the catalyst of choice in terms of conversion and regioselectivity,
