Polyene compounds of the formula: ##EQU1## wherein R' is protected or unprotected hydroxyl or a group of the formula: ##EQU2## (in which R" and R"' are each carboxyl or a group convertible into carboxyl on hydrolysis), m is a positive integer and n is 0 or a positive integer, which are useful as intermediates in the synthesis of coenzyme Q, can be produced advantageously through a step for the dehydration of a compound of the formula: ##EQU3## wherein R', m and n are each as defined above.
通式为##EQU1##的多烯化合物,其中R'为保护或未保护的羟基或通式为##EQU2##的基团(其中R"和R"'各自为羧基或可在
水解下转化为羧基的基团),m为正整数,n为0或正整数,这些化合物作为
辅酶Q合成中的中间体具有用途,可以通过通式为##EQU3##的化合物的脱
水步骤有利地制备,其中R'、m和n如上所定义。
