Provided according to the present invention is a process for the preparation of a polyprenol represented by the following formula (1):
wherein Y and Z individually represent a hydrogen atom or are coupled together to form a carbon-carbon bond; R represents a hydrogen atom or a protective group of a hydroxyl group; and n stands for 0 or an integer not smaller than 1, which comprises bringing an organic complex of an alkaline metal into contact with a compound represented by the following formula (2):
wherein concerning V, W and X, V represents a halogen atom, while W and X are coupled together to form a carbon-carbon bond or X represents a halogen atom, while V and W are coupled together to form a carbon-carbon bond; A represents a protective group of a hydroxyl group; and Y,Z and n have the same meanings as defined above.
根据本发明提供了一种制备下式(1)所代表的聚肾上腺素的工艺:
其中 Y 和 Z 分别代表氢原子或耦合在一起形成碳-碳键;R 代表氢原子或羟基的保护基团;n 代表 0 或不小于 1 的整数,该工艺包括使碱金属的有机络合物与下式(2)所代表的化合物接触:
其中关于 V、W 和 X,V 代表卤素原子,而 W 和 X 联接在一起形成碳-碳键,或 X 代表卤素原子,而 V 和 W 联接在一起形成碳-碳键;A 代表羟基的保护基团;Y、Z 和 n 的含义与上述定义相同。
