A method of making a 5-formylporphyrin, comprises the steps of: condensing a 5-acetaldipyrromethane with a dipyrromethane-1,9-dicarbinol to produce a porphyrin having an acetal group substituted thereon at the 5 position; and then hydrolyzing said porphyrin to produce said 5-formylporphyrin. Products and intermediates useful in such methods, along with methods of making such intermediates, are also described.
制备5-甲醛卟啉的方法包括以下步骤:将5-乙醛二吡咯甲烷与二吡咯甲烷-1,9-二羟基甲烷缩合,生成在5位上取代有缩醛基团的卟啉;然后水解所述卟啉,生成所述的5-甲醛卟啉。还描述了在这种方法中有用的产品和中间体,以及制备这种中间体的方法。
