1]pentadecatriene skeleton was investigated by employing cyclization reactions using two key precursors bearing acetylene cobalt complex. Cyclization for the synthesis of strained twelve-membered ring was achieved via Nicholas type reaction in reasonable yield. Reductive decomplexation of the dicobalt hexacarbonyl moiety of the cyclization product was achieved with n-Bu3SnH in the presence of a catalytic amount
通过使用两个带有乙炔钴配合物的关键前体的环化反应,研究了双环[9.3.1]十五碳三烯骨架的合成。通过Nicholas型反应以合理的产率实现了用于合成应变十二元环的环化。在1,4-环己二烯溶剂中催化量的NBS存在下,用n -Bu 3 SnH对环化产物的二钴六羰基部分进行还原分解。
