A protocol for the synthesis of 2,3-dihydrofurans by reductive denitrogenation/ringcontraction of 6-membered cyclic nitronates was developed. The process utilizes cheap Raney® nickel both as catalyst and stoichiometric agent without the need for high-pressure equipment. The products are formed in high purity and column chromatography is often not required. Studies on the substrate scope, functional
