Dihydropyrromethenone 67b, a potential precursor for the synthesis of phytochrome 1, has been prepared in enantiomerically pure form beginning with N-aminopyrrole 64 and the acetylenic acid 62b. The key step involved a 3,5-sigmatropic rearrangement of N-pyrrolo enamide 66b.

Pyrromethenones are prepared by a process involving acylation of an N-aminopyrrole with a suitable acetylenic acid, followed by sequential 5-exo-dig cyclization and 3,5-sigmatropic shift.
