1,3-Dipolar cycloaddition reaction of porphyrinoids using in-situ generated azomethine ylide has been well documented. The reaction usually ends up to the pi-extention of the mother macrocycles. We adopted these reactions to the pi-extention and chemical modification of meso-alkylidene porphyrins which we have synthesized recently. The reaction of in-situ generated azomethinee ylide (generated from the reaction of N-methyl glycine with formaldehyde) with alkylidene-(m-benzi)porphyrin or its expanded analogue resulted in a mixture of the cyclized adducts. The reaction took place regioselectively on the pyrrole adjacent to the alkylidenyl double bond in the case of porphyrinoids. However, the expanded analogues resulted different regiochemical adducts. All adducts were characterized by spectroscopic means. The regioselectivity was thought to be originated from the combination of strong dipolarophile) and electron rich pyrrole ring. The current synthetic methods can be applied to the construction of the reduced porphyrins which are useful in various porphyrin-related applications.
