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.

【期刊论文】Synthesis of C-7 oxidized abietane diterpenes from racemic ferruginyl methyl ether
潘鑫复, Anpai Li, Xuegong She, Jiyong Zhang, Tongxing Wu, and Xinfu Pan*
Tetrahedron 59(2003)5737-5741,-0001,():
-1年11月30日
A series of naturally occurring C-7 oxidized abietane diterpenes have been synthesized from racemic ferruginyl methyl ether in high yields. 6-Hydroxy1-5, 6-dehydrosugiol (7) can be converted into stable xanthoperol (12) using high temperature. Among the products, the structures of sugiyl methyl ether (2) and 6 (-hydroxysugiyl methyl ether (8) were determined by X-ray analysis.
