An alternative route to benziporphyrins has been developed. Reaction of an [Formula: see text]-unsubstituted pyrrole ethyl ester with isophthaloyl chloride in the presence of aluminum chloride afforded a diketone that underwent selective reduction with diborane to give a benzitripyrrane. Cleavage of the ethyl esters with sodium hydroxide in refluxing ethylene glycol, followed by acid catalyzed condensation

Recognition by strapped system: Cryptand‐type calix[4]pyrrole are shown to exhibit a highly enhanced affinity towards anionic guests as compared to other reported calix[4]pyrroles (see figure). The results obtained provide some insights as to how calix[4]pyrrole‐based anionreceptors may be designed to achieve higher affinity and selectivity.
