PdCl2-catalyzed intramolecular Heck reaction was conducted in ionic liquid, 1-n-butyl-3-methylimidazolium tetraborate ([BMIm] BF4), substituted benzofurans were obtained in modest to satisfactory yields. The ionic liquid containing Pd catalyst can be used four times with a little loss of activity.

An asymmetric and regioselective total synthesis approach to 1,4-benzodioxane lignans was reported in which (2R, 3R)-and (2S, 3S)-3-(4-hydroxy-3-methoxyphenyl)-2-hydroxymethyl-1, 4-benzodioxan-6-carbaldehyde were synthesized firstly. A natural-1, 4-benzodioxane neolignan was synthesized firstly by the synthesis approach.

【期刊论文】Total Synthesis of Two Naturally Occurring Bicyclo [3.2.1] octanoid Neolignans
潘鑫复, Mingyi Wang, †, Anxin Wu, Xinfu Pan, *, and Hongfang Yang†
J. Org. Chem. 2002, 67, 5405-5407,-0001,():
-1年11月30日
The first total syntheses of the racemates of naturally occurring macrophyllin-type bicyclo [3.2.1] octanoid neolignans, kadsurenin C 3 and kadsurenin L 4, were accomplished starting from vanillin and resorcinol. The acidcatalyzed rearrangement of hydrobenzofuranoid neolignans into bicyclo [3.2.1] octanoid neolignans was used as the key step.

【期刊论文】Pd/C-catalyzed Heck reaction in ionic liquid accelerated by microwave heating
潘鑫复, Xingang Xie, Jiangping Lu, Bo Chen, Junjie Han, Xuegong She*, and Xinfu Pan*
Tetrahedron Letters 45(2004)809-811,-0001,():
-1年11月30日
Pd/C-catalyzed Heck reaction was conducted in ionic liquid 1-octanyl-3-methylimidazolium tetrafluoroborate ([OMIm]BF4) in absence of phosphine ligand, which was promoted by microwave irradiation. The ionic liquid containing catalyst system can be used five times with a little loss of activity.
