A method of making a bacteriochlorin is carried out by condensing a pair of compounds of Formula II
to produce the bacteriochlorin, wherein R is an acetal or aldehyde group. The condensing may be carried out in an organic solvent, preferably in the presence of an acid. The bacteriochlorins are useful for a variety of purposes such as active agents in photodynamic therapy, luminescent compounds in flow cytometry, solar cells, light harvesting arrays, and molecular memory devices.

chlorin. Tetradehydrocorrins (ring-contracted tetrahydroporphyrins) are attractive for studies of catalysis analogous to that of vitaminB12. An eight-step synthesis toward such tetrahydroporphyrinic macrocycles begins with p-tolualdehyde and proceeds to a dihydrodipyrrin-acetal (1) bearing a geminal dimethyl group and a p-tolyl substituent. Self-condensation of 1 in CH3CN containing BF3·OEt2 at room
Asymmetric intramolecular Friedel–Crafts reaction catalyzed by a spiropyrrolidine organocatalyst: Enantioselective construction of indolizine and azepine frameworks
The asymmetric intramolecular Friedel–Crafts type Michael reaction of α,β-unsaturated aldehyde with pyrrole, catalyzed by a spiropyrrolidine (SP)-type organocatalyst, has been accomplished, which allows the construction of a series of azepine and indolizine frameworks with high to excellent enantioselectivities (up to 98% ee). Moreover, the substrate scope could be extended to generate a quaternary
Various dimethyl 3-substituted pyrrole-2, 4-dicarboxylates (3) were synthesized by the reaction of methyl isocyanoacetate (2) with methyl α-isocyanoacrylates (5) in the presence of base. This type of reaction was also applicable to the preparation of 3-substituted pyrrole-2, 4-dicarboxamides (10) by employing appropriate amide compounds (8) or (9) and (12) as reactants. Hydrolysis followed by decarboxylation of the pyrrole diester compounds (3) gave 3-substituted pyrroles (14) in good yields. A series of these compounds (14) showed antiinflammatory activities against carrageenan-induced rat paw edema. Among the compounds tested, 3-(2-chlorophenyl) pyrrole (14d) was found to be more potent than mefenamic acid.
