  • Palladium-catalyzed asymmetric synthesis of allylic alcohols from unsymmetrical and symmetrical racemic allylic carbonates featuring C–O-bond formation and dynamic kinetic resolution
    作者:Hans-Joachim Gais、Oleg Bondarev、Ralf Hetzer
    DOI:10.1016/j.tetlet.2005.07.044
    日期:2005.9
    Described is the asymmetric synthesis of the allylic alcohols 11 (85% ee), 15 (99% ee), 17 (93% ee), 19 (61% ee), and 21 (69% ee) through a Pd-catalyzed reaction of the unsymmetrical carbonates rac-10, rac-12, rac-14, rac-16, rac-18, and rac-20, respectively, with KHCO3 and H2O in the presence of bisphosphane 6. Similarly the allylic alcohols 23 (99% ee) and 25 (97% ee) have been obtained from the symmetrical

  • Palladium-Catalyzed Asymmetric <i>O</i>-1,5-Addition with Oximes via Hydroximation of Unsaturated Esters

    we disclose an electronically mismatched 1,5-conjugate addition process with oximes as the nucleophiles. By this design, the oxime moieties are readily introduced to the γ-position of the electron-deficient substrates in good yields, excellent regioselectivities, and high enantioselectivities. The corresponding allyl oximes are also conveniently transformed into a series of valuable enantioenriched

  • Conformational study of chiral alkenes: the influence of protective groups on the relative stability of ground-state rotational isomers
    作者:Benjamin W. Gung、Mark A. Wolf
    DOI:10.1021/jo00077a023
    日期:1993.12
    A variable temperature NMR study shows that a protective group on the hydroxy function of a chiral allylic alcohol can either enhance or counter the influence of the vinyl substituent on the ground-state (GS) conformations. If the allylic hydroxy is protected as a methyl ether, the CH-eclipsed form I becomes favored to a greater degree for normal chiral alkenes. Furthermore, conformer I becomes preferred even for the gamma-hydroxy-alpha,beta-unsaturated esters, which normally favor the CO-eclipsed form (II). On the other hand, the tert-butyldimethylsilyl (TBDMS) ether enhances the preference for conformer II for the gamma-hydroxy-alpha,beta-unsaturated esters and diminishes the preference for the CH-eclipsed form of normal chiral alkenes. These facts are explained by the size of the allylic oxygen lone pairs.
