抄録

20π Antiaromatic isophlorins of <I>N</I><SUP><I>21</I></SUP>,<I>N</I><SUP><I>22</I></SUP>-bridged <I>N</I><SUP><I>23</I></SUP>-alkyl-porphyrins were prepared through photoreduction with N-benzyl-1,4dihydronicotinamide or intramolecular nucleophilic alkylation at the N(24)-position. The ring structure of these <I>N</I><SUP><I>21</I></SUP>,<I>N</I><SUP><I>22</I></SUP>-bridged isophlorins is not highly deviated from planarity and their antiaromaticity was indicated by the great paramagnetic ring current effect.
