Intramolecular Pd-catalysed cyclisation reactions for the preparation of bicyclic compounds have been studied as a model system towards the synthesis of corialstonine and corialstonidine. Significant differences in reactivity have been observed for the cyclic allyl alcohols possessing O-protected and free OH functionalities. Cyclisation via the intramolecular Heck reaction, for both derivatives, proved
已经研究了分子内钯催化的环化反应以制备双环化合物,作为合成Corialstonine和Corialstonidine的模型系统。对于具有O-保护的和游离OH官能团的环状烯丙醇,已经观察到反应性的显着差异。对于这两种衍生物,通过分子内Heck反应的环化被证明是高度区域选择性的,并且当O-保护的化合物偏爱环化的外型时,未保护的醇优选内环化途径。为了获得对这些过程的进一步了解,进行了简短的计算研究。
