A pincer-ligated iridiumcomplex, (PCP)Ir (PCP = κ(3)-C6H3-2,6-[CH2P(t-Bu)2]2), is found to undergo oxidative addition of C(sp(3))-O bonds of methyl esters (CH3-O2CR'), methyl tosylate (CH3-OTs), and certain electron-poor methyl aryl ethers (CH3-OAr). DFT calculations and mechanistic studies indicate that the reactions proceed via oxidative addition of C-H bonds followed by oxygenate migration, rather

The invention generally relates to substituted benzofuranyl and substituted benzoxazolyl compounds, and more particularly to a compound represented by Structural Formula (I) or (II), or a pharmaceutically acceptable salt thereof, wherein the variables are as defined and described herein. The invention also includes the synthesis and use of a compound of Structural Formula A, or a pharmaceutically acceptable salt or composition thereof, e.g., in the treatment of cancer (e.g., mantle cell lymphoma), and other diseases and disorders.
The present invention is directed to certain hydroxamate derivatives that are inhibitors of histone deacetylase and are therefore useful in the treatment of diseases associated with histone deacetylase activity. Pharmaceutical compositions and processes for preparing these compounds are also disclosed.
