Abstract
Abstract: Three novel capped porphyrins (bicyclo [2.2. 2] octane-capped porphyrins, VIAH2 and VIBH,, and bicyclo [2.2. 2]-oct-7-ene-capped porphyrin, VICH,) have been successfully synthesized by the Lewis acid (BF,. Et, O) catalyzed condensation of pyrrole with tetraacetals 6, 12, and 15, respectively. IH and I3C 1D and'H-IH 2D NMR (DQF-COSY and ROESY) of porphyrins WAH2 and VIBH2 and IH 1D and 2D NMR of VICH2 established that the ...
