A novel domino reaction, alkyne-mediated domino hydroformylation/double cyclization, has been developed for rapid preparation of indolizidine type alkaloids. DFT calculations were applied for rationales of reactivity and selectivity. A concise synthesis of tashiromine as the application of the methodology is also reported.
一种新颖的多米诺反应——
炔烃介导的羰基化/双环化反应已开发用于快速制备
吲哚啉类
生物碱。本文还应用密度泛函理论计算来解释反应性和选择性的原理。此外,此方法学应用于塔什基碱的简洁合成也一并报道。
