Abstract
An efficient one-pot protocol for the direct conversion of free base 5,15-disubstituted porphyrins into the corresponding meso activated alkenyl-substituted meso-formylporphyrins has been developed using a sequential SNAr reaction with PyMe2SiCH2Li, conjugate addition to enones or alkenoates in the presence of TMSCl, and oxidation with DDQ.
