The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: H-Trp-OMe.HCl(SMILESS: N[C@@H](CC1=CNC2=CC=CC=C12)C(OC)=O.[H]Cl,cas:7524-52-9) is researched.Application In Synthesis of 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine. The article 《Catalytic dehydrative peptide synthesis with gem-diboronic acids》 in relation to this compound, is published in ACS Catalysis. Let’s take a look at the latest research on this compound (cas:7524-52-9).
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.
