Several procedures required for the preparation of porphyrins with labile side chains have already been referred to above or in the earlier article, for example, the conversion of acetoxyethyl or aminoethyl groups (introduced at the pyrrole stage) into vinyl groups. The preparation of porphyrin 3-keto esters has now been improved by the use of imidazolides (rather than acid chlorides) in condensations with magnesium methyl hydrogen malonate. The porphyrin acyl imidazolides have also been converted into acrylic esters by the sequence porCo-imidazole - -CH2OH — CHO - CH = CHC02Me. Alternatively the porphyrin ketoesters may be reduced with borohydride to hydroxyesters and dehydrated to acrylic esters. ...
