The reactions of pyridine-N-oxides with Ph3P under the developed conditions provide an unprecedented route to (pyridine-2-yl)phosphonium salts. Upon activation with DABCO, these salts readily serve as functionalized 2-pyridyl nucleophile equivalents. This umpolung strategy allows for the selective C2 functionalization of the pyridine ring with electrophiles, avoiding the generation and use of unstable

The present invention is concerned with substituted bicyclic heterocyclic compounds of Formula (I) wherein Het1, Het2, A1, A2, A3 and A4 have the meaning defined in the claims. The compounds according to the present invention are useful as gamma secretase modulators. The invention further relates to processes for preparing such novel compounds, pharmaceutical compositions comprising said compounds as an active ingredient as well as the use of said compounds as a medicament.
A regioselective α-heteroarylation followed by deoxygenation towards the synthesis of variety of azine triazole from simple azine N-oxides derivatives and N-tosyl-1,2,3-triazoles has been described. The reaction is metal free and basefree with shorter reaction time, high yields and a broad substrate scope.

An extensive kinetic study of selected key reactions of (oxidative) goldcatalysis concentrates on the decrease of the catalytic activity due to inhibition of the gold(I) catalyst caused by pyridine derivatives that are obtained as by‐products if N‐oxides are applied as oxygen donors. The choice of the examined pyridine derivatives and their corresponding N‐oxides has been made regardless of their
对(氧化)金催化的选定关键反应的广泛动力学研究集中在催化活性的降低,这是由于吡啶衍生物引起的金(I)催化剂的抑制,如果使用N氧化物作为副产物获得的吡啶衍生物氧气供体。不管它们的市售性如何,都已对受检吡啶衍生物及其相应的N-氧化物进行了选择。特别注意的是迄今为止在大多数反应筛选中都被忽略的实际益处。用GC和1监测测试反应1 H NMR光谱。所接收的反应常数提供了关于杂环的电子结构与催化活性之间的相关性的信息。根据收集的动力学数据,有可能开发出一套基本的三种N氧化物,这些氧化物必须在进一步的氧化金(I)催化反应中加以考虑。
