Water mediated trapping of active methylene intermediates generated by IBX-induced oxidation of Baylis-Hillman adducts with nucleophiles

Tan, Jia-Neng,Li, Haoquan,Gu, Yanlong

supporting information; experimental part, p. 1772 - 1782 (2011/02/21)

Water proved to be an efficient solvent for oxidation of a Baylis-Hillman adduct with IBX. The generated product, a methylene intermediate, could be trapped in situ by many nucleophiles in water, such as styrenes, β-dicarbonyl compounds, benzamide and les
