metal‐catalyzed ortho‐selective C(sp2)−H amidation of weakly coordinating aldehydes remains limited to precious metals such as Ir, Rh, Ru, etc. Herein, we put forward a novel report on ortho‐amidation of benzaldehydes employing user‐friendly dioxazolones under cost‐effective and air‐stable Cp*Co(III) catalysis. This catalytic transformation involves transient directing group strategy to enhance the ligating

The present invention provides methods of augmenting B cell depletion by promoting intravascular access of B cell subsets sequestered in lymphoid tissues rendering the B cells sensitive to killing mediated by the B cell depleting agent. One method of promoting intravascular access is by the use of integrin antagonists. Methods of treating B cell disorders by this approach is also provided.
Experimental and computational studies on H<sub>2</sub>O-promoted, Rh-catalyzed transient-ligand-free <i>ortho</i>-C(sp<sup>2</sup>)–H amidation of benzaldehydes with dioxazolones
We develop an efficient and convenient ligand-free, rhodium-catalyzed ortho-C(sp2)–H amidation of benzaldehydes with dioxazolones using H2O as the key promoter.
