Asymmetric hydrogenation of pyridines and subsequent N-alkylation lead to indolizidines and quinolizidines. The presence of Cl− results in retention of the absolute configuration of the initially formed alcohol. Noncovalent interactions, H-bonding, π-π stacking and electrostatic interactions also play important roles in regulating the stereoselectivity of the reaction process.
吡啶的不对称氢化和随后的 N-烷基化产生吲哚里西啶和喹里西啶。Cl -的存在导致最初形成的醇的绝对构型得以保留。非共价相互作用、氢键、π-π堆积和静电相互作用在调节反应过程的立体选择性方面也发挥着重要作用。
