13-Membered heterocyclic ring analogs of the core structure of manzamine alkaloids were synthesized by ring closing metathesis (RCM) reaction. The influence of a remote heteroatom (N, O, S) on E/Z stereochemistry of the olefinic double bond formed in RCM reaction using Grubbs 1st and 2nd generation ruthenium carbene complexes was evaluated. Studies show that RCM reaction is kinetically controlled and
通过闭环复分解(RCM)反应合成了曼扎明生物碱核心结构的13元杂环类似物。评估了远程杂原子(N,O,S)对使用第一和第二代钌卡宾络合物在RCM反应中形成的烯烃双键的E / Z立体化学的影响。研究表明,RCM反应是动力学控制的,杂原子影响双键的立体化学。
