摘要：In senescent leaves of higher plants, colorless chlorophyll (Chl) catabolites typically accumulate that belong to one of two major types, classified as formyloxobilin-type or dioxobilin-type phyllobilins (PBs). Natural yellow and pink colored formyloxobilin-type PBs are also known, named YCCs and PiCCs, respectively. A dioxobilin-type yellow Chl catabolite (DYCC) was recently prepared by partial synthesis, characterized by spectroscopic means and also identified in grapevine leaves. Here, we report the first dioxobilin-type pink Chl catabolite (DPiCC) from its partial synthesis from the DYCC. The DPiCC had similar structural features and absorption characteristics (in the visible spectral region) as the natural PiCC, its formyloxobilin-type analogon. In contrast to the effectively racemic PiCC, the DPiCC is an optically active pigment with a stable new asymmetric carbon center. [GRAPHICS] .
