Two monosubstituted and one tetrasubstituted N-confused porphyrins (1-3) were prepared in ca. 3-5% yields using a [2 + 2] synthesis. The monosubstituted porphyrins have carbomethoxy (1) or nitro (2) substituents on one of the meso-phenyl groups, while the meso-phenyl groups of the third NCP (3) are substituted with nitro, bromo, and methyl groups in an AB2C pattern. The specific regiochemistry of the aryl rings around the macrocycle in each porphyrin was definitively determined using a combination of 1D (1H and 13C) and 2D (gHMBC, gHSQC and ROESY) NMR spectroscopy. The absorption spectra of 1-3 in CH2Cl2 are similar to those of N-confused tetraphenylporphyrin (NCTPP) but have Soret and Q bands that are shifted to lower energies with smaller extinction coefficients in comparison to those for NCTPP.

Various 1-arylsulfonyl-3-(α-hydroxybenzyl)-1H-pyrroles were prepared by Friedel-Crafts reaction of 1-arylsulfonyl-1H-pyrroles with aroylchlorides in the presence of aluminum trichloride, followed by reduction of the ketones to the required carbinols. The compounds were identified as a novel class of non-nucleoside HIV-1 reverse transcriptase inhibitors characterized by the presence of a diarylcarbinol moiety, a chemical feature that strictly correlates with the anti-HIV-1 activity.
