摘要
The reaction of arenediazonium tetrafluoroborates with the THP derivative of (Z)-2-butene-1,4-diol in the presence of Pd(OAc)(2) in MeOH at 35 degrees C gives 4-aryl-2-methoxytetrahydrofurans in good to high yields. The reaction tolerates it variety of useful functional groups including ester, keto, cyano. nitro. chloro. and bromo functionalities as well as ortho substituents. Based on this process, gamma-aryl-beta-butyrolactone derivatives can be prepared via a sequential palladium-catalyzed arylation-cyclization-oxidation protocol that omits the isolation of 4-aryl-2-methoxytetrahydrofuran intermediates.
