Five routes to stable chlorins bearing 0 or 1 meso substituents have been investigated, among which reaction of a 9-bromo-1-formyldipyrromethane and 2,3,4,5-tetrahydro-1,3,3-trimethyldipyrrin proved most effective. Application of this route afforded metallochlorins [Cu(II), Zn(II), Pd(II)] including the chlorin lacking any beta-pyrrole and meso substituents.
已研究出五种途径制得带有0或1个内消旋取代基的稳定二氢卟酚,其中9-溴-1-甲酰基二吡咯甲烷与2,3,4,5-四氢-1,3,3-三甲基二吡咯啉的反应被证明是最有效的。应用该途径可得到金属氯霉素[Cu(II),Zn(II),Pd(II)],包括缺乏任何β-吡咯和内消旋取代基的二氢卟酚。
