Ruthenium-catalyzed β-alkylation of secondary alcohols with primary alcohols
Bai, Wei,Jia, Guochen
, p. 234 - 241 (2015/06/02)
The catalytic properties of a series of ruthenium complexes for β-alkylation of secondary alcohols with primary alcohols were studied. The catalytic activities of the ruthenium complexes were found to be dependent on the auxiliary ligands. The most active catalytic precursor found in this study is the ruthenium complex RuCl2(PPh3)2(2-NH2CH2Py) [2-NH2CH2Py = 2-aminomethyl pyridine], which effectively catalyzed the β-alkylation of both aryl- and alkyl-substituted secondary alcohols with benzylic and alkyl primary alcohols.
A convenient methodology for the chemoselective reduction of a wide variety of functionalized alkenes
Babler, James H.,White, Nicholas A.
experimental part, p. 439 - 441 (2010/03/04)
An efficient method to effect chemoselective reduction of alkenes (including trisubstituted olefins) possessing various sensitive and/or reducible groups such as acetals, allylic alcohols, benzyl ethers, epoxides, esters, halides, nitriles, and sulfones is reported. The reduction is facile at 0 °C in aqueous N,N-dimethylacetamide containing sodium borohydride in the presence of 15 mol % ruthenium(III) chloride. Regioselective reduction of dienes is also feasible if the double bonds are sufficiently different in their structural environment.
Titanocene-catalyzed regiodivergent epoxide openings
Gansaeuer, Andreas,Fan, Chun-An,Keller, Florian,Keil, Jutta
, p. 3484 - 3485 (2008/01/01)
The first regiodivergent opening of unbiased epoxides providing the ring-opened products in high enantiomeric excess from racemic and exceptionally high enantiomeric excess from enantioenriched substrates in a double asymmetric process has been devised. It constitutes a more general case of the very important enantioselective openings of meso-epoxides. Copyright
