Alkane-gem-diboronic acids have emerged as versatile organoboron catalysts for dehydrative amidation of α-amino acids. A phenol-substituted multiboron catalyst with a B-C-B structure outperformed simple arylboronic acids in the condensation of α-amino acids with suppressed epimerization of electrophiles. gem-diboronic acid catalysis were compatible with various O, N, and S-functionalized α-amino acids bearing N-protecting groups including common carbamates used in peptide synthesis (Boc, Cbz, Fmoc). Gem-Diboronic acid catalysis were compatible with various O, N, and S-functionalized α-amino acids bearing N-protecting groups including common carbamates used in peptide synthesis (Boc, Cbz, Fmoc). N-trifluoroacetyl protection enabled an unprecedented catalytic dehydrative peptide synthesis at room temperature Preliminary mechanistic studies revealed carboxylate-binding nature of gem-diboronic acids, orthogonal to the activation of carboxylic acids by arylboronic acids. The distinctive reactivity of the gem-diboronic acids would open prospects for mild catalytic peptide condensation. The experimental part of the paper was very detailed, including the reaction process of H-Trp-OMe.HCl(cas: 7524-52-9Product Details of 7524-52-9)
H-Trp-OMe.HCl(cas:7524-52-9) is one of amino acid derivatives. Amino acid derivatives represent an important category of skin penetration promoters. These compounds possess hydrophobic chains attached to an amino acid headgroup via a biodegradable ester bond. Due to the amphiphilic nature of these derivatives, it is possible for them to enter into the SC lipid barrier and significantly disorganize skin membrane lipids.Product Details of 7524-52-9
