A cobalt-catalyzed 1,4-aryl migration/disulfonylation cascade applied to α-bromo N-sulfonyl amides was developed. The reaction was highly chemoselective, allowing the preparation of α-aryl amides possessing a variety of functional groups. The method was used as the key step to synthesize an alkaloid, (±)-deoxyeseroline. Mechanistic investigations suggest a radical process.

The synthesis of sterically hindered anilines has been a significant challenge in organic chemistry. Here we report a Cu-catalyzed radical addition with in situ-generated nitroso compounds to prepare sterically hindered amines directly from readily available materials. The transformation is conducted at room temperature, uses abundant copper salts, and is tolerant of a range of functional groups.

Phase-transfer-catalyzed (PTC) reactions of ketones with bromoform and aqueous lithium hydroxide in alcoholic solvent result in the formation of ,-unsaturated carboxylic acids. The reaction was performed at room temperature for 24h. The corresponding conj
Facile synthesis of 3,3-dialkyl-6-phenyl-imidazopyridinones

, p. 1237 - 1249 (2008/02/01)
A series of novel 3,3-dialkylated imidazopyridinones bearing 6-aryl groups were designed as mimetics of active progesterone antagonists, 3,3-disubstituted-5-arylindoles. The four-step synthetic route is described. The key steps are base-catalyzed cyclizat
Homolytic aromatic substitution: A radical approach towards the synthesis of 5-azaoxindoles
Storey, John M.D.,Ladwa, Mitesh M.
, p. 381 - 383 (2007/10/03)
A range of 5-azaoxindoles have been synthesised employing homolytic aromatic substitution onto pyridine as the pivotal step.
