A new, concise synthesis of the CCR-5 receptor antagonist maraviroc (UK-427,857) from 3-phenyl-1-propanol has been completed in four steps featuring a site-selective C–H functionalization.

We outline a strategy to enable non-directed Pd(II)-catalyzed C-H functionalization in the presence of Lewis basic heterocycles. In a high-throughput screen of two Pd-catalyzed C-H acetoxylation reactions, addition of a variety of N-containing heterocycles is found to cause low product conversion. A pyridine-containing test substrate is selected as...

Predicting site selectivity in C-H bond oxidation reactions involving heteroatom transfer is challenged by the small energetic differences between disparate bond types and the subtle interplay of steric and electronic effects that influence reactivity. Herein, the factors governing selective Rh2(esp)2-catalyzed C-H amination of isoamylbenzene deriv...

This chapter offers a general review of selective methods for the oxidative conversion of C–H to C–N bonds. Special focus has been given to the many disparate catalyst types that are capable of promoting this unique transformation.
