Chemical Communications, 2011•pubs.rsc.orgReaction of meso-tetraphenylporpholactone with hydrazine converts the lactone moiety to
an N-aminolactam. It also reduces the opposite pyrrolic moiety of both the starting material
and the N-aminolactam, generating chlorin-like chlorolactone and N-aminochlorolactam,
respectively. Reductive N–N cleavage of the N-aminoporpholactam generates the parent
porpholactam.
