The 15-tert-butyl-5-oxophlorin 1 forms a stable, neutral
π-radical species 2, in high yield; the 13,17-bis-unsubstituted
5-oxophlorin analogue 5, under similar conditions, affords the
15-iso-5-oxophlorin 6 and 15-hydroxy compound 7 (both characterized by
X-ray crystallography), the latter demonstrating the trapping of the
π-radical by dioxygen.
