Abstract: Abstract A new aromatic diamine, 4-(4-trifluoromethylphenyl)-2,6-bis[4-(4-amino-2-trifluoromethylphenoxy)phenyl]pyridine (9FPBAPP), was prepared from 4-(4-trifluoromethylphenyl)-2,6-bis(4-hydroxyphenyl)pyridine with 2-chloro-5-nitrotrifluoromethylbenzene by substitution and reduction reactions successively. A series of fluorinated copoly(pyridine ether imide)s were prepared from 4,4′-oxydianiline (ODA), pyromellitic dianhydride and 9FPBAPP… read more here.

DOI: 10.1021/acs.orglett.2c01295
Abstract: We report the fluorenylmethoxycarbonyl (Fmoc) protection of functionalized bis-amino acid building blocks using a temporary Cu2+ complexation strategy, together with an efficient multikilogram-scale synthesis of bis-amino acid precursors. This allows the synthesis of stereochemically and… read more here.
