  • Evaluating β-amino acids as enantioselective organocatalysts of the Hajos–Parrish–Eder–Sauer–Wiechert reaction
    作者:Stephen G. Davies、Angela J. Russell、Ruth L. Sheppard、Andrew D. Smith、James E. Thomson
    DOI:10.1039/b711171a
    日期:——
    A systematic study of the effect of substitution within the β-amino acid framework indicates that both β2- and β3-amino acids catalyse the Hajos–Parrish–Eder–Sauer–Wiechert reaction with poor to reasonable levels of enantioselectivity. These results led to the evaluation of the conformationally constrained β-amino acid (1R,2S)-cispentacin, which catalyses the Hajos–Parrish–Eder–Sauer–Wiechert reaction with comparable or higher levels of enantioselectivity to L-proline.
    对β-氨基酸框架内取代效应的系统研究表明,β2-和β3-氨基酸催化Hajos–Parrish–Eder–Sauer–Wiechert反应的对映选择性较低至合理。这些结果促使对构象受限的β-氨基酸(1R,2S)-cispentacin进行评估,该氨基酸催化Hajos–Parrish–Eder–Sauer–Wiechert反应的对映选择性与L-脯氨酸相比相当或更高。

    and enantioselective process for the double cascade synthesis of highly substituted 2-alkyl-cyclopentane-1,3-diones, 2-alkyl-3-methoxy-cyclopent-2-enones and Hajos-Parrish (H-P) ketone analogs is presented via reductive alkylation chemistry. For the first time, we have developed a single-step alkylation of cyclopentane-1,3-dione with aldehydes/ketones and a Hantzsch ester through an organocatalytic reductive
