β-Nitroacrylates as Precursors of Tetrasubstituted Furans in a One-Pot Process and under Acidic Solvent-Free Conditions

摘要

The reaction of α-functionalized carbonyl derivatives with β-nitroacrylates, catalyzed by acidic alumina and in the ab-sence of solvent, allows the one-pot synthesis of tetrasubstituted fu-ran derivatives, in which at least two powerful functionalities are present in the 3- and 4-positions.
