6-Oxopyriphlorins.
Young AM, Lash TD. Young AM, et al. Org Biomol Chem. 2013 Oct 21;11(39):6841-8. doi: 10.1039/c3ob41506f. Org Biomol Chem. 2013. PMID: 24175332
Reaction of 2,6-pyridinedicarbaldehyde with a series of tripyrranes in the presence of trifluoroacetic acid, followed by oxidation of a pyriphlorin intermediate with silver(I) acetate, gave 6-oxopyriphlorins in moderate to good yields. The oxophlorin analogues were …

Reduction of cysteine-S-protecting groups by triisopropylsilane.
Ste Marie EJ, Hondal RJ. Ste Marie EJ, et al. J Pept Sci. 2018 Nov;24(11):e3130. doi: 10.1002/psc.3130. J Pept Sci. 2018. PMID: 30353614 Free PMC article.
Here, we provide strong evidence that TIS can act as a reducing agent to facilitate the removal of acetamidomethyl (Acm), 4-methoxybenzyl (Mob), and tert-butyl (Bu(t) ) protecting groups from cysteine (Cys) residues in the presence of trifluoroacetic acid (TFA …
