The present invention relates to a process for preparing a porphyrin of formula (I), optionally in the form of a salt with an alkali metal and/or in the form of a metal complex:
in which:
R and R′ are as defined in claim
1
,
comprising:
a step of condensation, in an acidic medium, between a dipyrromethane of formula (II):
in which R′b is as defined above for (I),
and a dipyrromethane of formula (III):
in which R″ is as defined in claim
1
, and also the compounds of formula (III).
本发明涉及一种制备公式(I)的卟啉的方法,可选地以碱金属的盐形式和/或金属配合物的形式存在:
其中:
R和R′如权利要求1中定义的那样,
包括:
在酸性介质中,通过公式(II)的二吡咯甲烷和公式(III)的二吡咯甲烷之间的缩合步骤:
其中R′b如上述(I)中定义的那样,
以及公式(III)的化合物。
