• An efficient preparation of β-dimethylaminovinyl sulfone and sulfoximide, and investigation of their reactivity as dipolarophiles

  N'-dimethylamino)ethenyl)-S-phenyl-N-(p-tolylsulfonyl) sulfoximide in high yields is described. A reversal in regioselectivity was observed when the β-dimethylaminovinyl sulfone was employed as a dipolarophile in cycloadditions with nitrile oxides. The sulfone gives rise mainly to 4-substituted isoxazoles, after elimination of dimethyl amine. In comparison, phenyl vinyl sulfone cycloadds to give 5-substituted isoxazolines

  提供（E）-1-二甲基氨基-2-苯基磺酰基乙烯和S -（（E）-2-（N'，N'-二甲基氨基）乙烯基）-S-苯基-N-（p的简单反应描述了高收率的（甲苯磺酰基磺酰基）亚磺酰亚胺。当将β-二甲基氨基乙烯基砜用作腈类氧化物与环加成反应中的双极性亲和性时，观察到了区域选择性的逆转。消除二甲胺后，砜主要生成4-取代的异恶唑。相比之下，苯基乙烯基砜环加成生成5-取代的异恶唑啉。尽管在与腈氧化物和腈酰亚胺反应中未显示出可比的偶极亲液活性，但β-二甲基氨基乙烯基亚磺酰亚胺易于转化为S -（（E）-（3-乙氧基羰基）丙-2-烯基）-S-苯基-N-（p-甲苯基磺酰基）亚磺酰亚胺。该烯丙基磺酰亚胺酰亚胺环以良好的收率加入到苯甲腈氧化物和二苯基腈酰亚胺中，但是在该过程中未观察到立体选择性。在苯甲腈氧化物的情况下，仅能检测到适度的区域选择性。

  commonly serve as core structures of many therapeutic agents and natural products. However, the metal-free and catalysis-free strategy for the synthesis of these privileged motifs at room temperature remains a challenging task. Herein, we report a three-component strategy to afford diverse isoxazolines and isoxazoles via [3 + 2] cycloadditions of in situ-formed nitronates and olefins/alkynes under visible-light

• Magtrieve™ (CrO2) and MnO2 mediated oxidation of aldoximes: studying the reaction course

  Magtrieve (TM) (CrO2) and MnO2 mediated oxidation of aldoximes to nitrile oxides were studied in details. In presence of external radical source, TEMPO, these reagents did not furnish nitrile oxides, instead favoured deoximation to aldehydes. A common trend of deoximation was established from electronically tuned aldoximes, which is: aliphatic>aromatic>aldoximes with strong electron-withdrawing group, though the extent of deoximation was less in case of CrO2. Above effects were not observed with chloramine-T and diacetoxyiodobenzene, reagents known to produce nitrile oxides via hydroximoyl halide or equivalent ionic intermediates. A putative reaction mechanism is proposed for MO2 (M=Cr, Mn) mediated oxidation of aldoximes through formation of a nitroso-oxime tautomeric pair. Formation of nitrile oxide is possibly occurred from the oxime tautomer via a sigma-type iminoxy radical intermediate. The deoximation process, dominating in presence of external radical environment, is explained following decomposition of the nitroso tautomer. (C) 2010 Elsevier Ltd. All rights reserved.
