Atom-Economical Ni-Catalyzed Diborylative Cyclization of Enynes: Preparation of Unsymmetrical Diboronates
Cabrera-Lobera, Natalia,Quirós, M. Teresa,Brennessel, William W.,Neidig, Michael L.,Bu?uel, Elena,Cárdenas, Diego J.
, p. 6552 - 6556 (2019/08/20)
We report a Ni-catalyzed diborylative cyclization of enynes that affords carbo- and heterocycles containing both alkyl- and alkenylboronates. The reaction is fully atom-economical, shows a broad scope, and employs a powerful and inexpensive catalytic Ni-b
Iron-Catalyzed Hydroborylative Cyclization of 1,6-Enynes
Cabrera-Lobera, Natalia,Rodríguez-Salamanca, Patricia,Nieto-Carmona, Juan C.,Bu?uel, Elena,Cárdenas, Diego J.
, p. 784 - 788 (2017/11/29)
We report first Fe-catalyzed hydroborylative cyclization reaction. The process provides one C?C and one C?B bond in a single operation and shows a wide scope, allowing the formation of carbo- and heterocycles containing a homoallylic boryl unit that can b

supporting information; experimental part, p. 3403 - 3406 (2009/04/07)
Microwave-assisted Rh-diphosphane-complex-catalyzed dual catalysis is reported. This cooperative process provides [2+2+1] cycloadducts by sequential decarbonylation of aldehyde or formate and carbonylation of enynes within a short period of time. Various
Formate as a CO surrogate for cascade processes: Rh-catalyzed cooperative decarbonylation and asymmetric Pauson-Khand-type cyclization reactions
Lee, Hang Wai,Chan, Albert S. C.,Kwong, Fuk Yee
, p. 2633 - 2635 (2008/02/08)
A rhodium-(S)-xyl-BINAP complex-catalyzed tandem formate decarbonylation and [2 + 2 + 1] carbonylative cyclization is described; this cooperative process utilizes formate as a condensed CO source, and the newly developed cascade protocol can be extended t
Iridium-catalyzed cascade decarbonylation/highly enantioselective Pauson-Khand-type cyclization reactions
Kwong, Fuk Yee,Lee, Hang Wai,Lam, Wai Har,Qiu, Liqin,Chan, Albert S.C.
, p. 1238 - 1252 (2007/10/03)
An easily accessible chiral iridium-BINAP complex can effect the cooperative processes of decarbonylation of an aldehyde and cascaded enantioselective Pauson-Khand-type reaction. A survey of ligands revealed that atropisomeric aryl-diphosphine ligands wer
Rhodium-bisbenzodioxanphos complex-catalyzed homogeneous enantioselective Pauson-Khand-type cyclization in alcoholic solvents
Fuk, Yee Kwong,Hang, Wai Lee,Qiu, Liqin,Wai, Har Lam,Li, Yue-Ming,Hoi, Lun Kwong,Chan, Albert S. C.
, p. 1750 - 1754 (2007/10/03)
The chiral atropisomeric diphosphane ligand (S)-BisbenzodioxanPhos was found to be highly effective in the co-operative processeses of aldehyde decarbonylation and cascaded enantioselective Pauson-Khand-type reactions. Various 1,6-enynes were transformed
Rhodium-catalyzed asymmetric aqueous Pauson-Khand-type reaction
Kwong, Fuk Yee,Li, Yue Ming,Lam, Wai Har,Qiu, Liqin,Lee, Hang Wai,Yeung, Chi Hung,Chan, Kin Shing,Chan, Albert S. C.
, p. 3872 - 3880 (2007/10/03)
An interesting rhodium-catalyzed asymmetric aqueous Pauson-Khand-type reaction was developed. A chiral atropisomeric dipyridyldiphosphane ligand was found to be highly effective in this system. This operationally simple protocol allows both catalyst and r
