  摘要：

  根据反应中使用的醇助溶剂，γ-不饱和酮会经历由碘化sa（II）介导的两个非常不同的立体选择性环化反应。只需将醇助溶剂从甲醇更改为叔丁醇，即可在前所未有的羟醛螺环化和新型环丁醇形成工艺之间进行切换。[反应：看文字]

  Natural α-methylenelactam analogues: Design, synthesis and evaluation of α-alkenyl-γ and δ-lactams as potential antifungal agents against Colletotrichum orbiculare

  摘要：

  In our continued efforts to improve the potential utility of the alpha-methylene-gamma-lactone scaffold, 62 new and 59 known natural alpha-methylenelactam analogues including alpha-methylene-gamma- lactams, alpha-arylidene- gamma and delta-lactams, and 3-arylideneindolin-2-ones were synthesized as the bioisosteric analogues of the amethylenelactone scaffold. The results of antifungal and cytotoxic activity indicated that among these derivatives compound (E)-1-(2, 6-dichlorobenzyl)-3-(2-fluorobenzylidene) pyrrolidin-2-one (Py51) possessed good selectivity with the highest antifungal activity against Colletotrichum orbiculare with IC50 - 10.4 mu M but less cytotoxic activity with IC50 - 141.2 mu M (against HepG2 cell line) and 161.2 mu M ( against human hepatic L02 cell line). Ultrastructural change studies performed by transmission electron microscope showed that Py51 could cause important cell morphological changes in C. orbiculare, such as plasma membrane detached from cell wall, cell wall thickening, mitochondria disruption, a dramatic increase in vacuolation, and eventually a complete loss in the integrity of organelles. Significantly, mitochondria appeared one of the primary targets, as confirmed by their remarkably aberrant morphological changes. Analysis of structureeactivity relationships revealed that incorporation of the aryl group into the alpha-exo methylene and the N-benzyl substitution increased the activity. Meanwhile, the alpha-arylidene-gamma-lactams have superiority in selectivity over the 3-arylideneindolin-2-ones. Based on the results, the N- benzyl substituted a-(2-fluorophenyl)-gamma-lactam was identified as the most promising natural- based scaffold for further discovering and developing improved crop- protection agents.

• An Expeditious Route to Both Enantiomers of All Carbon Quaternary Stereocenters at C-3 Carbon of Lactams via [3,3]-Sigmatropic Rearrangement: Total Synthesis of (−)-Physostigmine

  A diastereoselective route to all carbon quaternary stereocenters at the C-3 position of cyclic lactams has been developed via Johnson–Claisen rearrangement of γ-hydroxy-α, β-unsaturated lactams. It has been observed that olefin geometry plays an important role in the development of the absolute stereochemistry of the product. The dependence of the product configuration on the olefin geometry is explained

• Inhibition of the pore-forming protein perforin by a series of aryl-substituted isobenzofuran-1(3H)-ones

  An aryl-substituted isobenzofuran-1(3H)-one lead compound was identified from a high throughput screen designed to find inhibitors of the lymphocyte pore-forming protein perforin. A series of analogs were then designed and prepared, exploring structure-activity relationships through variation of 2-thioxoimidazolidin-4-one and furan subunits on an isobenzofuranone core. The ability of the resulting compounds to inhibit the lytic activity of both isolated perforin protein and perforin delivered in situ by intact KHYG-1 natural killer effector cells was determined. Several compounds showed excellent activity at concentrations that were non-toxic to the killer cells. This series represents a significant improvement on previous classes of compounds, being substantially more potent and largely retaining activity in the presence of serum. (C) 2011 Elsevier Ltd.
