The demethyl analogues (1d,e) of dpep have been prepared by utilizing in each case an oxidative cyclization of an intermediate biladiene -ac to assemble the porphyrin macrocycle.
The synthesis of three octapyrrolic, 810, and four dodecapyrrolic, 1518, oligomers is reported. They are linear poly(dipyrromethene)s and potential ligands as building blocks for supramolecular architectures through self-assembly. Octapyrrolic oligomers 810 were prepared in 9095% yields by condensation of 2 equiv of a tripyrrolic compound 4 with 1 equiv of diformyldipyrrolic compounds 57. A similar procedure, involving the condensation of 2 equiv of a pentapyrrolic starting material 13 with 1 equiv of 57 or 14, was found to give rise to the corresponding dodecameric systems 1518 in 4156% yields.Key words: poly(dipyrromethene), linear polypyrroles, dipyrromethane, dipyrromethene.
