Hu, Yi,Ding, Qiuping,Ye, Shengqing,Peng, Yiyuan,Wu, Jie
supporting information; experimental part, p. 7258 - 7262 (2011/10/08)
An efficient palladium-catalyzed cross-coupling reaction of 4-hydroxy-pyrone or 4-hydroxy-2(5H)-furanone with arylboronic acid is described, which affords the 4-substituted-pyrones and 2(5H)-furanones in good yields. This transformation proceeds through a C-OH bond activation under mild conditions.

An efficient and facile synthesis of 4-substituted 2(5H)-furanones using palladium catalyzed cross-coupling reactions between 4-tosyl-2(5H)-furanone and boronic acids is reported herein.

Bistributylstannyl-2(5H)-furanone 4a has been prepared from 3-(tetrahydropyran-2-yl)oxy but-2-ynoate and shown to exhibit good selectivity in its Stille reactions with a range of halogenated compounds, leading to 4-substituted-3-stannyl-2(5H)-furanones, in generally moderate yield. Under certain reaction conditions, doubly substituted products were also isolated from the reactions. The 3,4-bistrimethylstannyl furanone, 4b, corresponding to 4a was prepared, but decomposed during all attempts to execute Stille reactions upon it.
An expedient palladium-mediated route to 3-arylfurans
Taniguchi, Takahiko,Nagata, Hiroshi,Kanada, Regina Mikie,Kadota, Kohei,Takeuchi, Miwako,Ogasawara, Kunio
, p. 67 - 71 (2007/10/03)
A facile route to 3-arylfurans has been developed by employing the Heck reaction between 2,5-dihydro-2,5-dimethoxyfuran and aryl iodides as the key step.
Reductive Carbonylation of Acetylenes under Water-Gas Shift Reaction Conditions. Synthesis of Furan-2(5H)-ones from Terminal and Non-substituted Acetylenes
Joh, Takashi,Nagata, Hiroyuki,Takahashi, Shigetoshi
, p. 1305 - 1308 (2007/10/02)
Under water-gas reaction conditions terminal and non-substituted acetylenes are selectively converted into furan-2(5H)-ones by catalysis with a rhodium carbonyl cluster.
