Ligand effects in selective carbonyl addition reactions of organomanganese and cerium reagents
Reetz, Manfred T.,Haning, Helmut,Stanchev, Stephan
, p. 6963 - 6966 (1992)
Transmetalation of organolithium reagents RLi (R = CH3, n-Bu) with manganese pivalate produces reagents of the type RMnOC(O)tBu which react stereoselectively with substituted cyclohexanones to afford the axial alcohols preferentially. These rea
Ligand effects on diastereoselective addition of organocerium reagents to aldehydes and cyclic ketones
Greeves, Nicholas,Lyford, Lisa,Elizabeth Pease
, p. 285 - 288 (2007/10/02)
A new class of chiral dialkoxy- and diaryloxyorganocerium reagent has been prepared and the diastereoselectivity of carbonyl addition reactions has been compared with that of conventional organocerium reagents.
Unprecedented Stereoselectivity in the Addition of Organoiron(II) Reagents to Cyclohaxanone Derivatives
Reetz, Manfred T.,Stanchev, Stephan
, p. 328 - 330 (2007/10/02)
Various organoiron(II) reagents undergo Grignard-type additions to substituted cyclohexanone derivatives, C-C bond formation occurring stereoselectively from the equatorial direction (97 - 100percent selectivity).
Cleavage of Carbon-Carbon Bonds with High Stereochemical Control. 5. Course of the Haller-Bauer Reaction of Cyclic α-Phenyl Ketones
Paquette, Leo A.,Ra, Choon Sup
, p. 4978 - 4985 (2007/10/02)
The Haller-Bauer cleavages of three ketones, (R)-(+)-3-benzoyl-3-phenyl-1-isopropylidinecyclopentane (9) and the cis- and trans-1-benzoyl-1-phenyl-4-tert-butylcyclohexanes (16 and 25), have been studied with different base and solvent systems.Whereas the
