An efficient synthesis of carbo-and heterocycles using CC, CO and CN bonds under cobalt catalysis is described. The substituents on olefins are key for controlling the regio-and chemoselectivity in the initial hydrogen atom transfer step and quaternary carbons are efficiently constructed under mild conditions. Cyclopropane cleavage and tandem cyclization give highly functionalized bicyclic skeletons in a single operation.
Oxidative cyclization of alkenoic acids promoted by AgOAc
Carrillo-Arcos, Ulises A.,Rojas-Ocampo, Jonathan,Porcel, Susana
, p. 479 - 483 (2016/01/09)
Alkenoic acids derived from salicylic acid and analogues undergo an unexpected oxidative cyclization process triggered by AgOAc leading to 4H-benzo[d][1,3]dioxin-4-ones. The process is affected by the substitution on the aryl and the allyl units.
Regioselective silver-mediated Kondakov-Darzens olefin acylation
Barczak, Nicholas T.,Jarvo, Elizabeth R.
supporting information; experimental part, p. 12912 - 12916 (2011/12/04)
Enone construction: A silver-mediated olefin acylation reaction is described, in which five-, six-, and -seven-membered rings, tetrasubstituted olefins, bridged bicycles, spirocycles, and benzoxepinones are prepared. Highly selective intermolecular reactions are coupled to a Nazarov cyclization for the effective preparation of cyclopentenones, including the core of modhephene (see scheme). Copyright
