We recently described two novel arylbindingsites of farnesyltransferase. In this study, the cinnamoyl residue was designed as an appropriate substituent for our benzophenone‐based AAX‐peptidomimetic compound capable of occupying the fararylbindingsite.

general strategy for the intermolecular synthesis of polysubstituted cyclopentenones using palladium catalysis. Overall, this reaction is achieved via a molecular shuffling process involving an alkyne, an α,β-unsaturated acid chloride, which serves as both the alkene and carbon monoxide source, and a hydrosilane to create three new C-C bonds. This newcarbon monoxide-free pathway delivers the products
我们描述了使用钯催化分子间合成多取代环戊烯酮的一般策略。总体而言,该反应是通过涉及炔烃、α,β-不饱和酰氯(作为烯烃和一氧化碳来源)和氢硅烷的分子改组过程实现的,以产生三个新的 CC 键。这种新的无一氧化碳途径提供了具有优异产量的产品。此外,区域选择性是对环戊烯酮合成常规方法的补充。此外,还提出了一组区域和化学发散反应,以强调这种新策略的合成潜力。

[3.2]paracyclophane (10), [4.2]paracyclophane (14), [4.3]paracyclophane (19) as well as several derivatives of these compounds – among others the bromides 25, the ester 31, the diesters 40–43 – are described using well-established methods of cyclophane chemistry (ring-closure reactions leading to thiacyclophanes, ring contraction by sulfone pyrolysis). The parent systems and their derivatives are now
