摘要:Seven phthalides, including a new dimeric one named tokinolide C (7), were isolated from Angelicae Sinensis Radix and characterized. The structures of these compounds were elucidated on the basis of comprehensive analysis of spectroscopic data and comparison with literature d...

摘要:... We have shown that chemometric resolution using gas chromatographic- mass spectrometry (GC–MS) could be used for the qualitative and quantitative analysis of the majority of Terpenoids or Phthalides from herb formulae and single herbs. A GC × GC system was further opt...

摘要:The marine-derived fungus Stachylidium sp. was isolated from the sponge Callyspongia sp. cf. C. flammea. Culture on a biomalt medium supplemented with sea salt led to the isolation of three new phthalide derivatives, i.e., marilones A–C ( 1 – 3 ), and the known compound silv...

摘要:Abstract(#br)This study evaluated the potential anti-inflammatory effects of natural phthalides, isolated from Ligusticum porteri , and of semi-synthetic phthalides. Anti-inflammatory activity was investigated in two mouse models; one with ear edema, induced with 12- O -tetradeca...

摘要:Phthalides are important bio-active constituents in Si-Wu-Tang and Fo-Shou-San, two commonly used Traditional Chinese Medicine (TCM) combined prescriptions mainly derived from Radix Angelica and Rhizoma Chuanxiong. In this paper, the contents of eight phthalides, including Z-l...

摘要:Abstract(#br)A series of new phthalides of pharmacological interest were synthesized by a protocol involving condensation of two γ-keto acids, 2-(4-isopropylbenzoyl)benzoic acid ( 1a ) and 2-(4-isopropyl-3-nitrobenzoyl)benzoic acid ( 1b ) with phenolic compounds in the pres...

摘要:Abstract(#br)The ruthenium-catalyzed intermolecular cascade cyclization of aromatic acids with aromatic aldehydes, which involves the direct insertion of C–H bond into a polar C=O bond and the successive intramolecular nucleophilic substitution, was developed for the synthesis of 3-substituted phthalides...

摘要:Abstract(#br)A highly diastereoselective and enantioselective Michael addition/desymmetrization reaction of maleimides with prochiral 3- substituted phthalides catalyzed by quinine-derived bifunctional thiourea was realized. A broad range of the 3,3′-disubstituted phthalides...

摘要:Abstract(#br)The reductive coupling of phthalic anhydrides with acetone by Zn-TiCl 4 in THF gave two-to-one and one-to-one coupled products. The coupled products were transformed to 3,3-diisopropyl-, 3-isopropylidene-, and 3-isopropylphthalides. In addition, the reductive couplin...
