报道了辛可宁催化的MBH(Morita-Baylis-Hillman)碳酸酯β位和吡唑酮的不对称烯丙基烷基化反应.在温和的条件下,此反应以良好的产率(55%~91%)和最高93%的对映选择性得到了一系列手性吡唑酮类化合物.
The asymmetric allylalkylation of cinchonine-catalyzed β-position of MBH (Morita-Baylis-Hillman) carbonate with pyrazolone catalyzed by cinchonine has been reported in good yields (55% -91% %) And up to 93% gave a series of chiral pyrazolones.
