Cobalt-Catalyzed Cross-Coupling of 3- and 4-Iodopiperidines with Grignard Reagents

A cobalt-catalyzed cross-coupling between 3- and 4-iodopiperidines and Grignard reagents is disclosed. The reaction is an efficient, cheap, chemoselective, and flexible way to functionalize piperidines. This coupling was used as the key step to realize a short synthesis of (±)-preclamol. Some mechanistic investigations were conducted that highlight the formation of radical intermediates. Scaffold synthesis: A cobalt-catalyzed cross-coupling between iodopiperidines and Grignard reagents is reported (see scheme; PG=protecting group). A large variety of 3- and 4-substituted piperidines were synthesized and the method was applied to a short synthesis of (±)-preclamol. This work constitutes one of the rare examples of cross-couplings involving 3-halogeno piperidines.

Iron- and cobalt-catalyzed arylation of azetidines, pyrrolidines, and piperidines with grignard reagents

Iron- and cobalt-catalyzed cross-couplings between iodo-azetidines, -pyrrolidines, -piperidines, and Grignard reagents are disclosed. The reaction is efficient, cheap, chemoselective and tolerates a large variety of (hetero)aryl Grignard reagents.

Selective C-F bond activation: Substitution of unactivated alkyl fluorides using YbI3

F makes the break: The carbon-fluorine single bond is quite strong, thus making aliphatic C-F bond scission unusually challenging. A new methodology utilizing YbI3 leads to the conversion of a C-F bond into a C-I bond, and is compatible with various functional groups. The reaction is exceptionally selective towards alkyl fluorides and proceeds under mild conditions. Copyright
