An efficient approach for the construction of one C—N bond and one C=N bond based on sulfonyl hydrazides, 3,4-dihalo-2(5H)-furanones and carbonyl compounds via the one-pot strategy to provideN-2(5H)-furanonyl sulfonyl hydrazone products with good yields is described. This approach with wide substrate range and good selectivity can be achieved at room temperature by metal-free catalysts. Even for 3,4-dichloro-2(5H)-furanones, the inactive Csp2—Cl type compounds, this green method also gives satisfactory yields. Importantly, its application for a gram-scale preparation of different furanone substrates can be accomplished.

Key words: 2(5H)-furanone, sulfonyl hydrazone, synthesis, one-pot reaction, metal-free catalysis
