Enantioselective short formal synthesis of (+)-precapnelladiene (1) was achieved from a bicyclo[3.2.0]heptane derivative, which was prepared enantioselectively by chiral copper-catalyzed [2+2]-cycloaddition reaction of 2-methoxycarbonyl-2-cyclopenten-1-one with phenylthioacetylene developed by us.
由双环[3.2.0]庚烷衍生物可实现对映选择性短形式的(+)-precapnelladiene(1)合成,该衍生物是通过2-甲氧基羰基-2-的手性铜催化的[2 + 2]-环加成反应对映选择性制备的我们开发的环戊烯-1-酮与苯硫基乙炔。
