Pyrroles can serve as competent nucleophiles with meso electrophiles in the Pd-catalyzed asymmetric allylic alkylation. The products from this transformation were obtained as a single regio- and diastereomer in high yield and enantiopurity. A nitropyrrole-containing nucleoside analogue was synthesized in seven steps to demonstrate the synthetic utility of this transformation.
在 Pd 催化的不对称烯丙基烷基化中,吡咯可以作为有能力的亲核试剂和中观亲电试剂。来自该转化的产物以高产率和对映体纯度作为单一区域和非对映异构体获得。含硝基吡咯的核苷类似物分七个步骤合成,以证明这种转化的合成效用。
