A series of long wavelength photosensitizers related to chlorins and bacteriochlorins has been synthesized from the Diels-Alder reaction of protoporphyrin III dimethyl ester 6, or protoporphyrin II dimethyl ester 29.These porphyrins were prepared either b

In connection with studies of substrate specificity of uroporphyrinogen decarboxylase and coproporphyrinogen oxidase, enzymes in the heme and chlorophyll biosynthetic pathways,and heme oxygenase,an enzyme involved in the catabolism of hemes,we have synthesized a number of new porphyrins substituted with acetic,propionic,and butyric side-chains,using the a,c-biladiene route;one porphyrin was also prepared by the MacDonald pyrromethane approach.In one of the a,c-biladiene cyclizations,meso-chlorinated porphyrins were formed as minor by products,but this side-reaction was suppressed by carefully drying the copper(II) chloride used in this stage, or by use of copper(II) acetate as an alternative oxidant.

α-Acetoxymethylpyrroles couple with α-free pyrroles in presence of Montmorillonite clay to form unsymmetrical pyrromethanes in excellent yields. Symmetrical pyrromethanes were also prepared in a similar manner by clay catalysed self-condensation of α-acet
