Synthesis of bronzaphrin NS

摘要

The chemistry of porphyrin analogs and homologs has enjoyed a period of extended growth. Most of the isomers of porphyrin [1.1.1.1]have now been synthesized, as well as a number of sapphyrin, corrin, and other macorocycles fitting the broad definition of "pentaplanar". "Penta- planar" is a term describing an aromatic macrocycle consistiong of five-membered rings linked by sp~2-hybrid- ized atoms.
