Guo, Zong-Liang,Zhong, Shi,Li, Yong-Bo,Lu, Gui
experimental part, p. 238 - 245 (2011/05/04)
The catalytic asymmetric Henry reaction of nitromethane to various aldehydes has been developed using a chiral binaphthylazepine derived amino alcohol and Cu(OAc)2·H2O as the catalyst. High yields and good enantioselectivities (up to
A highly diastereo-and enantioselective copper(I)-catalyzed henry reaction using a bis(sulfonamide)-diamine ligand
Jin, Wei,Li, Xincheng,Wan, Boshun
experimental part, p. 484 - 491 (2011/04/15)
A series of bis(sulfonamide)-diamine (BSDA) ligands were synthesized from commercially available chiral α-amino alcohols and diamines. The chiral BSDA ligand 3a, coordinated with Cu(I), catalyzes the enantioselective Henry reaction with excellent enantios
Dual-reagent organocatalysis with a phosphine and electron-deficient alkene: application to the Henry reaction
Wang, Xiu,Fang, Fan,Zhao, Chen,Tian, Shi-Kai
scheme or table, p. 6442 - 6444 (2009/04/06)
Triphenylphosphine in combination with methyl acrylate was found to be able to catalyze the Henry (nitroaldol) reaction of various aldehydes and α-keto esters to give the corresponding β-nitroalkanols in good to excellent yields, and a catalytic cycle involving a zwitterionic phosphine-alkene adduct was proposed for this dual-reagent organocatalysis according to the deuterium-labeling experiments with CD3NO2.

Enantioselective synthesis of α,α-disubstituted amines from nitroalkenes
Leroux, Mary-Lorene,Le Gall, Thierry,Mioskowski, Charles
, p. 1817 - 1823 (2007/10/03)
Disubstituted nitroalkenes were converted into enantiomerically enriched amines (isolated as their hydrochloride salts) with enantiometric excesses of 88 to >95% in there steps: (a) highly stereoselective conjugate addition of the potassium salt of 4-phenyloxazolidin-2-one; (b) radical-mediated removal of the nitro group; (c) cleavage of the oxazolidinone.
Potassium Exchanged Layered Zirconium Phosphate as Base Catalyst in the Synthesis of 2-Nitroalkanols
Constantino, U.,Curini, M.,Marmottini, F.,Rosati, O.,Pisani, E.
, p. 2215 - 2218 (2007/10/02)
The synthesis of 2-nitroalkanols from nitroalkanes and aldehydes occurs efficiently, in mild conditions without solvent, when mediated by layered Zr(KOPO3)2.The reaction has been tested in the preparation of ten different nitroalkanols and the data obtain
Inter- and Intramolecular Cycloadditions of Nitroalkenes with Olefins. 2-Nitrostyrenes
Denmark, Scott E.,Kesler, Brenda S.,Moon, Young-Choon
, p. 4912 - 4924 (2007/10/02)
Aromatic nitroalkenes 9 - 12 underwent Lewis acid catalyzed cycloadditions with various cyclic alkenes to afford high yields of nitronates 25 - 30 with exclusive anti selectivity.Hammett studies helped to further delineate the role of the Lewis acid.Reaction of nitroalkenes 8 and 10 with various cyclic dienes in the presence of a Lewis acid demonstrated the ability of nitroalkenes to behave as dienes in cycloadditions.The major products were the syn diastereomers which arise from an endo-folded transition structure.Finally, intramolecular cycloaddition of 36 - 39 allowed a correlation between the stereochemical course of the reaction and positions of sp2 centers in the tether to be addressed.
PREPARATION OF ACYCLIC NITRO OLEFINS FROM β-TRIMETHYLSILOXY NITRO COMPOUNDS
Lee, Kilsung,Oh, Dong Young
, p. 3055 - 3060 (2007/10/02)
An efficient process for the preparation of acyclic nitro olefins is described, which consisted of improved nitro aldol reaction to give β-trialkylsiloxy nitro compounds and the direct or indirect elimination of water.
