摘要：An N-confused phlorin isomer bearing a dipyrrin moiety at the alpha-position of the confused pyrrole ring (1) was synthesized. Pd-II and B-III coordination at the peripheral prodigiosin-like moiety of 1 afforded the corresponding complexes 2 and 3. Reflux of 2 in triethylamine (TEA) converted the meso-phenyl into the Pd-II-coordinating phenoxy group to afford 4. Under the same reaction conditions, TEA was linked to the alpha-position of the dipyrrin unit in 3 as an N,N-diethylaminovinyl group to afford 5. Furthermore, peripheral coordination of B-III in 3 and 5 improved the planarity of the phlorin macrocycle and thus facilitated the coordination of Ag-III at the inner cavity to afford 3-Ag and 5-Ag, respectively. These results provide an effective approach for developing unique porphyrinoids through peripheral coordination.
