Stereoselektive Synthese des Nitrit‐reduzierenden Cofaktors Häm d1 ausgehend von Hämatoporphyrin

Abstract: The nitrite-reducing cofactor heme d, has been synthesized in a few synthetic steps, starting from readily accessible hematoporphyrin dimethyl ester (rac-4a). A single-crystal structure analysis of the synthesized target molecule rac-l0a unequivocally established the constitution and the relative configuration of heme d, (3). 1. Einleitung. -Isobakteriochlorine 1, die als charakteristisches Strukturelement zwei benachbarte, partiell gesattigte Pyrrol-Ringe im Porphyrin-Grundgerust besitzen, sind in der Natur d… Show more

“…β-Carbonyl functionalities are also found in nature. One example carrying two β-carbonyl functionalities on adjacent pyrrolic moieties is heme d 1 , the prosthetic group of bacterial nitrous oxide, sulfite, and nitrite reductase. An example with two β-carbonyl functionalities on opposite pyrrolic building blocks is represented by the family of tolyporphins, green tetrapyrrolic pigments of unknown function isolated from a cyanobacterium-microbial ecological unit. …”

“…164 Most isobacteriochlorin structures include a geminal dialkyl group for stabilization as well. Examples are 81, 165 169,170 Others are those with an exocyclic double bond, e.g. 86, 171 An example for a compound derived from Pheo a is the nickel(II) complex of anhydromesorhodoisobacteriochlorin methyl ester 87, with a typical ruf core conformation.…”
