hydroxide‐catalyzed hydrosilylation exhibits excellent activity and chemoselectivity for the reduction of cyclic imides under mild reaction conditions. The chemoselectivity of the reduction system may be readily tuned by changing the identity and stoichiometry of the hydrosilanes: a polymethylhydrosiloxane (PMHS)/potassium hydroxide reduction system resulted in the reduction of various cyclic imides to

catalytic system has been illustrated for the synthesis of Diels–Alder adduct for the first time. This procedure tolerates substrate diversity and delivers high yield. Use of environmentally benign catalyst, high yields and substrate diversity are the highlight of the existing method. Graphic Abstract Ca(OTf)2, along with n-Bu4NPF6 as the co-catalyst, is shown to be an effective Lewis acidic catalyst
摘要 Ca(OTf)2 / Bu 4 NPF 6催化体系首次被证明用于Diels-Alder加合物的合成。此过程可耐受底物多样性并提供高产量。使用环境友好的催化剂,高产率和底物多样性是现有方法的重点。 图形摘要 Ca(OTf)2和n- Bu 4 NPF 6作为助催化剂,被证明是一种有效的路易斯酸性催化剂体系,用于Diels-Alder反应。除了可持续和高效之外,此过程还很健壮,并且以接近定量的产量获得了产品。

The present invention relates to peptidomimetic compounds that inhibit serine protease activity, particularly the activity of hepatitis C virus NS3-NS4A protease. As such, they act by interfering with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The invention further relates to compositions comprising these compounds either for ex vivo use or for administration to a patient suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a patient by administering a composition comprising a compound of this invention.
Provided herein is a method for enzymatically triggered assembly of polymeric nanostructures for detection of cancer-associated enzymes in vivo. By detecting enzymatic signals associated with disease, one can sensitively determine the site, and extent of disease within a patient.
