A simple and general synthetic strategy potentially applicable for the preparation of a wide variety of unsymmetrically N,N'-bis(substituted)-4, 13-diaza-18-crown-6-ether derivatives was reported.

In a single step and in 95% yieldpyrene can be converted into pyren-4-ylaceticacidfrom which subsequently cyclopenta[c,d]pyrene (CPP) can be obtained in an overall yield of 60%.
