    Direct Catalytic Asymmetric Aldol Additions of Methyl Ynones. Spontaneous Reversal in the Sense of Enantioinduction
    摘要:
    In this Communication, we report the direct, catalytic, asymmetric aldol addition of methyl ynones using our dinuclear zinc catalyst. A spontaneous reversal in the sense of enantioinduction was observed for these reactions; formation of the (S)-enantiomer is favored in the early stages (69% ee after 5 min), whereas the (R)-enantiomer is isolated as the major product after prolonged reaction times (97% ee after 22 h). It could be shown that this reversal in enantioselectivity is due to formation of a new catalytic species which incorporates the aldol product.

  • Intramolecular 4+3 cycloadditions. Vinylthionium ions from allylic alcohols
    作者:Michael Harmata、Darin E. Jones

    日期:1996.2
    Aldehyde 9 can be prepared from ethyl pyruvate in several steps. Treatment of 1 with various diene-containing Grignard reagents results in the formation of the corresponding allylic alcohol in good yield. Exposure of these alcohols to triflic anhydride results in the formation of 4+3 cycloadducts in good to excellent yields. Furan and simple butadiene trap the intermediate allylic cation efficiently in
