描述了一种有效的规程,用于使用Cu(OAc)2催化剂和黄原酸酯作为硫源,通过α-C–H官能化,从易于获得的2-碘对二苯并呋喃中合成2-酰基苯并[ b ]噻吩。反应性较低的2-溴查耳酮也以良好的产率产生相应的2-酰基苯并噻吩。该反应通过硫的原位结合进行,然后进行铜催化的环化反应,生成没有外部酰基源的2-酰基苯并噻吩。合成的重要性通过1-(5-羟基苯并噻吩-2-基)乙酮的合成得到了展示,这是一种已知的mRNA前剪接调节剂。

This invention relates to the discovery of novel compounds, or pharmaceutically acceptable salts thereof, which possess HDAC inhibitory activity. In particular, the compounds of the invention demonstrate selectivity towards Class I HDAC enzymes, and are accordingly expected to be useful for their anti-proliferative activity and in methods of treatment of the human or animal body, for example in preventing or inhibiting tumour growth and metastasis in cancers. The invention also relates to processes for the manufacture of the compounds defined herein, or pharmaceutically acceptable salts thereof, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments for use in the production of an anti-proliferative effect in a warm-blooded animal such as man.
An efficient method for the synthesis of (E)-1H-inden-1-ones using gold-catalyzed tandem [3,3]-propargyl esterrearrangement followed by Michael addition under mild reaction conditions has been developed. The resulting products are important frameworks found in numerous natural products and pharmaceutically active compounds, as well as being valuable intermediates in organic synthesis.

novel palladium-catalyzed hydration–olefin insertion cascade assisted by internal nucleophiles was developed for the synthesis of biologically significant 2,3-dihydro-1H-inden-1-ones under mild conditions. A detailed mechanistic study revealed that the assistance of the internal nucleophiles is crucial to trigger the cascade reaction via nucleopalladation of the alkyne moiety. The overall reaction is
Novel palladium catalysed two- and three-component thermal (conventional heating and microwave) cascade processes are described involving allenylation of an aryl iodide to generate a (π-allyl)palladium species, which are intercepted (inter- or intramolecularly) by a carbon or nitrogen nucleophile followed by intramolecular Michael addition to afford carbo- and heterocycles in good yields.
