Anaerobic functionalization of unactivated C-H bonds.

ABSTRACT: The functionalization of alkanes was once thought to lie strictly within the domain of enzymes that activate dioxygen in order to generate an oxidant with suitable potency to cleave inert C-H bonds. The emergence of the radical SAM superfamily of enzymes-those which use S-adenosyl-l-methionine as a precursor to a 5'-deoxyadenosyl 5'-radical-has kindled a renaissance in the study of radical-dependent enzymatic reactions, and is ushering in a wealth of new and intriguing chemistry that remains to be elucidated. This review will focus on a special subclass of radical SAM enzymes that functionalize inert C-H bonds, highlighting the functional groups and the chemistry that leads to their insertion. Within this class are first, enzymes that catalyze sulfur insertion, the prototype of which is bi
