Methodology for synthesis of symmetrical or unsymmetrical porphyrin dimers linked at the meso positions with phenyl or stilbene functionalities is reported; 5-porphyrinyl-dipyrromethanes are key intermediates in this approach.
The application of photoannelation reactions to synthesis has been of growing importance and interest in recent years: by the use of these methods with
Hinokiflavone (I) has been reported' as the sole example of naturally occurring biflavonyl ether. We now report a new type of biflavonyl ether isolated from Ochna squarrosa Linn. (Ochnaceae) and named ochnaflavone (II). Although biflavones so far isolated have been obtained mostly from gymnosperm,
