Synthesis of a C-15-Substituted Porphyrin from a b-Bilene Precursor

Article abstract of DOI:10.1021/jo00371a011

The synthesis of a porphyrin substituted at C-13 with an ethoxycarbonyl residue and at C-15 with a β-(methoxycarbonyl)methyl side chain was attempted using a b-meso-substituted b-bilene-1',8'-di-tert-butyl ester precursor.The latter was obtained by conden
