Reaction 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 …

Reaction of known meso-tetraarylporpholactone free bases 3, made from the corresponding
porphyrins, with hydrazine produces three products: It converts the lactone functional group …

meso-Tetraaryl-2, 3-dihydroxychlorins (1) were converted in one step to the novel free base
macrocycles meso-tetraaryl-2, 3-dialkoxy-2a-oxa-2a-homoporphyrins (morpholinochlorins …

The rational syntheses of meso-tetraaryl-3-oxo-2-oxaporphyrins 5, known as
porpholactones, via MnO4–-mediated oxidations of the corresponding meso-tetraaryl-2, 3 …

The formal replacement of a pyrrole moiety of meso-tetraarylporphyrin 1 by an oxazole
moiety is described. The key step is the conversion of porpholactones 4 (prepared by a …

meso-Tetrahexylporphyrin was converted to its corresponding 7, 8-dihydroxychlorin using
an osmium tetroxide-mediated dihydroxylation strategy. Its diol moiety was shown to be able …

The porphodimethene rearrangement methodology reported in this paper provides for a
rational, step-by-step synthesis of chlorins from readily available pyrrole precursors. The …

The reaction of meso-tetrakis (pentafluorophenyl) porpholactone with azomethine ylides and
nitrones affords pyrrolidine-fused and isoxazolidine-fused dihydroporpholactones that …

Using mildly basic reaction conditions, the periodate-induced diol cleavage of meso-
tetraphenyl-2, 3-diolchlorin allows for the generation and isolation of the corresponding …
