Acylation of Aryl Halides and α-Bromo Acetates with Aldehydes Enabled by Nickel/TBADT Cocatalysis
摘要:
In this protocol aryl halides and alpha-bromo acetates are efficiently cross-coupled with an array of (hetero)aromatic and aliphatic aldehydes under the cooperative catalysis of nickel and tetrabutylammonium decatungstate as a hydrogen-atom-transfer photocatalyst. This method provides a concise approach to a variety of ketones with high compatibility of various functional groups.

This invention relates to quinolyloxazole-2-ones which are useful anti-enveloped virus agents by virtue of their ability to act as protein kinase C inhibitors. These derivatives are disclosed to be effective in treating enveloped virus infections including HIV infections and are thus useful in the treatment of AIDS and ARC.
