title: Sparsely substituted chlorins as core constructs in chlorophyll analogue chemistry. I. Synthesis.
abstract: 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.
