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.

摘要

The stereoisomers of 3, 4-dihydroxy-6-methoxy-2, 2-dimethyl-chroman 1a-c and 3, 4, 7-trihydroxy-6-acetyl-2, 2-dimethylchroman 2a-c were conveniently prepared for the first time via a synthesis in which Sharpless asymmetric dihydroxylation and Jacobsen's catalytic asymmetric epoxidation are the key steps.

摘要

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.

摘要

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.
