The first metalated porphyrazinediols 11 have been prepared from (L)-(+)-dimethyl tartrate via conversion into the corresponding dispoke or 2,3-dimethoxy-2,3-butanediyl protected 2,3-dihydroxymaleonitrile, Linstead macrocyclization, transmetalation, and deprotection. Their stability is very dependent on the nature of the metal ion in the cavity of the porphyrazine. Reaction of these porphyrazinediols

A series of enantiomericallypure porphyrazineoctaol derivatives have been prepared from l-(+)-dimethyl tartrate via conversion into the corresponding dispoke protected dihydroxymaleonitrile, Linstead macrocyclization and transmetallation. The derived chloromanganese(III) complexes catalyzed the epoxidation of styrene with sodium hypochlorite as the oxygen atom source but with modest enantioselectivities
