, p. 76 - 83 (2011)
The active catalysts for the enantioselective ring opening (ARO) of meso-stilbene oxide, cis-butene oxide, cyclohexene oxide, cyclopentene oxide, and cyclooctene oxide with various substituted anilines were generated in situ by the reaction of Ti(Oi

A class of N-(naphthalen-1-yl)-N′-alkyl oxalamides have been proven to be powerful ligands, making a coupling reaction of (hetero)aryl iodides with primary amines proceed at 50 °C with only 0.01 mol % of Cu2O and ligand as well as a coupling reaction of (hetero)aryl bromides with primary amines and ammonia at 80 °C with only 0.1 mol % of Cu2O and ligand. A wide range of coupling partners work well under these conditions, thereby providing an easy to operate method for preparing (hetero)aryl amines.

, p. 629 - 634 (2014/03/21)
Ferrocenium tetrafluoroborate [Fe(Cp)2BF4] is an efficient Lewis acid catalyst for the aminolysis of aromatic, aliphatic, and cyclic epoxides using aniline and substituted anilines as the nucleophile to provide regioselective β-amino alcohols in 61-97% yields under solvent-free conditions at room temperature. The ring opening of cyclohexene oxide with aliphatic amines gave 2-aminocyclohexanols in 33-98% yields at 60 °C under solvent-free conditions. Georg Thieme Verlag Stuttgart New York.

Bis-TADDOLs as bifunctional organocatalysts for trifluoromethylation of aldehydes and ring-opening of cyclohexene oxide with p-toluidine
Belokon, Yuri N.,Gugkaeva, Zalina T.,Maleev, Victor I.,Moskalenko, Margarita A.,North, Michael,Tsaloev, Alan T.
experimental part, p. 1793 - 1796 (2010/10/05)
A set of bis-TADDOLs, in which two TADDOL moieties are connected by different linkers, have been prepared. A great dependence of the catalytic activities of the bis-TADDOLs on the distance between the TADDOL moieties was found by the addition of trifluoromethyltrimethylsilane to benzaldehyde and ring-opening of cyclohexene oxide with or without alkali metal salts added.
Vanadium-salan catalyzed enantioselective ring opening of meso-epoxides with aromatic amines
Sun, Jiangtao,Dai, Zhenya,Yang, Minghua,Pan, Xu,Zhu, Chengjian
body text, p. 2100 - 2104 (2009/04/03)
The first example of enantioselective ring-opening of meso-epoxides catalyzed by chiral oxovanadium(V) - salan complexes is reported. The reaction furnished 1,2-aminoalcohols in good yields and moderate to high enantioselectivities (up to 87%). Thieme Stu
