✦ Synopsis

Dipyrromethane-2,10-dicarboxylates have been prepared. While oxidation and subsequent reaction of 5b with BF 3 •OEt 2 yields the corresponding complex 10, ring-closing metathesis of 5d using (NHC)(PCy 3 )(Cl) 2 Ru CHPh 7 results in the novel hybrid macrocycle 8. The structure of 10 has been unequivocally established by an X-ray crystallographic study.

## Abstract Dimethyl 3‐[(4‐nitro)phenyl]aziridine‐2,2‐dicarboxylate (3a) represents a new, photochromic aziridine. 3a and related aziridines undergo cycloadditions with dipolarophiles to form five‐membered heterocycles and react with nucleophiles with cleavage of the C^2^C^3^ bond.
