5-Unsubstituted 2-Pyrrolecarboxaldehydes for Porphyrin Synthesis and the Cyanovinyl Protecting Group

(Cyanovinyl)pyrroles (13) derived from the Knoevenagel condensation of benzyl 5-formyl-2-pyrrolecarboxylates (12) with methyl cyanoacetate were employed in a facile sequence of four steps to produce, regioselectively, 5-unsubstituted 2-pyrrolecarboxaldehy
A convenient synthetic route to the bacteriochlorin chromophore

The reactions of an A,C-divinylporphyrin with activated dienophiles yield stable bis Diels-Alder adducts absorbing light at wavelengths above 735 nm. This provides a convenient general route to bacteriochlorin-like chromophores.
