有人提出将六氢-2 H-噻吩并[2,3- c ]吡咯用作低分子量极性支架,以构建用于寻找新药的化合物库。该双环支架的衍生物的实用合成方法是基于[3 + 2]由N-苄基-1-甲氧基-N -(((三甲基甲硅烷基)甲基)甲胺和4-取代的2,3-二氢噻吩生成的内酰胺的环加成反应而开发的1,1-二氧化物。所有的3-取代的六氢-2 H-噻吩并[2,3 - c ]吡咯1,1-二氧化物衍生物均作为单一非对映异构体获得。hexahydro-2 H -thieno [2,3- c的构象性质使用X射线衍射研究探索了]吡咯1,1-二氧化物衍生物。证明了支架产生3D形分子文库的潜力。

日期:2007.8
A stable and storable precursor of 2-SF5-butadiene, 3-SF5-3-sulfolene, has been synthesized and its reactivity studied with several olefinic compounds. When SF5Br is added to sulfolene, 3-bromo-4-SF5-sulfolane is formed and when reacted further with silver tosylate forms 4-SF5-2sulfolene. The 4-SF5-2-sulfolene undergoes rearrangement with silicic acid to give 3-SF5-3-sulfolene and when heated forms 2-SF5-butadiene; in the absence of a dienophile, dimerization does occur. The new 2-SF5-butadiene is a reactive diene undergoing a Diels-Alder reaction with olefinic sytems such as maleic anhydride, p-naphthoquinone, and methyl acrylate.(c) 2007 Elsevier B.V.
