Direct formylation of enol ethers using cyanuric chloride and N,N-dimethylformamide

Hou, Duen-Ren,Sun, Chong-Si,Sie, Wu-Sian,Jian, Jing-Yu,Hsu, Yun

, p. 671 - 674 (2004)

A new method to prepare α,β-unsaturated enol aldehydes is described. 3-Ethoxymethacrolein (1) and 5-formyl-3,4-dihydro-2H-pyran (5) were effectively prepared from enol ethers and the Vilsmeier-Haack type complex, derived from cyanuric chloride and DMF. One byproduct, amidine 4, was also characterized.
