yield. The porphyrin gave a highly modified UV–vis absorption spectrum with three strong bands showing up in the Soret region and a series of Q bands that extended beyond 700 nm. The proton NMR spectrum also showed a significantly reduced diamagneticringcurrent where the meso-protons gave resonances near 9.3 ppm instead of typical porphyrin values of 10 ppm.

with diformyldipyrrylmethanes 19 under modified MacDonald “2 + 2” conditions gave good yields of meso,β-propanoporphyrins 26. This chemistry was sufficiently versatile that a porphyrin with two six-membered exocyclic rings (34) could be prepared by the same methodology. On the other hand, attempts to cyclize an a,c-biladiene 37 incorporating a six-memberedcarbocyclicring gave moderate to poor yields
