    Enone structure as a probe to Lewis acid carbonyl binding in copper-catalysed asymmetric conjugate addition
    摘要:
    Systematic changes in the substitution pattern of linear enones ((RCOCH)-C-1=CHR2) helps identify the reactive conformation (s-trans versus s-cis) of the enone in copper-catalysed asymmetric 1,4-ZnEt2 addition. Pointers to the binding mode of the Lewis Acid (syn or anti to the 'ene' function) are also gathered. Enantioselectivities of up to 79% have been realised in these reactions.

    日期:2010.12.17
    results suggest that retro-Diels–Alder reactions of tricyclodecadienones are catalyzed by Brønsted acids and the high catalytic performance of H-Beta catalysts can be ascribed to the optimal balance between the number of acid sites and their strength as well as to the accessibility of these sites. The methodology was then applied to a series of alkyl derivatives of cyclopentadienylcyclopentenones to provide
