  • Method of synthesizing 5,15-diarylbenzochlorin-7-one compounds
    Patent number: 5780622
    Abstract: A novel 5,15-diarylbenzochlorin-7-one compound having the formula (I) or (II): ##STR1## wherein M is a metal. A novel method for synthesizing the compound of formula (I) comprises the steps of:a. cyclizing a meso-(formylvinyl) 5,15-diarylporphyrin to form a cyclization reaction mixture, andb. oxidizing said reaction mixture to form the 5,15-diarylbenzochlorin-7-one of formula (I).A novel method for synthesizing the compound of formula (II) comprises the cyclizing and oxidizing steps listed above and, either prior to or after the oxidizing step, adding the step of demetallating the compound.
