  摘要：

  在真菌Geniculosporium的头空间提取物中检测到了两种未经鉴定的氯化挥发性化合物X和Y。它们的质谱指向X为氯二甲氧基苯，Y为二氯二甲氧基苯的结构。X和Y的一些构造异构体的质谱已包含在我们的数据库中，证明它们非常相似，因此无法完全确定结构。为了明确结构，我们通过合成或从商业供应商处获得了X和Y的所有可能的构造异构体。质谱和气相色谱保留时间的比较严格确定了这两种氯化挥发性化合物的结构。氯化挥发性化合物并不是很常见，但溴化或甚至碘化的挥发性化合物更为罕见。令人惊讶的是，从Streptomyces chartreusis的头空间提取物中发现了甲基2-碘苯甲酸酯，这是一种新的天然产物，丰富了碘化天然产物家族。

  The sulfonamide analogs 17 and 21 were found to be much more potent COX-2 inhibitors and orally active anti-inflammatory agents than the corresponding methyl sulfone analogs 16 and 20, respectively, albeit with some decrease in COX-2 selectivity. Structure-activity relationship studies have determined that incorporation of two fluorine atoms in the central phenyl group, as in 20 and 21, is extremely

  palladium-catalyzed tandem reaction for the one-pot synthesis of 9H-carbazoles under microwave irradiation is developed. This approach involves a sequential Buchwald–Hartwig amination and a direct arylation from affordable and inexpensive anilines and 1,2-dihaloarenes. For the development of this purpose, a novel and magnetically recoverable palladium nanocatalyst supported on a green biochar under ligand-free

  and 1,4‐dimethoxybenzenes, 1,2,3‐trimethoxybenzenes and most of their chlorinated derivatives and some related brominated compounds were measured for CDCl3 solutions. The 17O NMR chemical shifts show up to 60 ppm dispersion. Comparison between the compounds with and without adjacent chlorine atoms (2,6‐di‐ and 2,4,6‐tri‐substitution) also showed a clear methoxy carbon chemical shift change. The number
