“…Starting from commercially available d -glucurono-6,3-lactone and 4-hydroxyphenethyl bromide, NATOG was synthesized. d -Glucurono-6,3-lactone was converted to the glycosylation acceptor methyl 2,3,4-tri- O -acetyl-1- O -(trichloroacetimidoyl)-α- d -glucopyranuronate, and 4-hydroxyphenethyl bromide was converted to the donor 4-(2-azidoethyl)­phenol, on the basis of literature procedures. , This donor/acceptor pair was coupled in the presence of the activator boron trifluoride etherate at −78 °C and warmed to room temperature to yield 2-(4-(2-azidoethyl)­phenoxy)-6-(methoxycarbonyl)­tetrahydro-2 H -pyran-3,4,5-triyl triacetate. NATOG was isolated as a white powder following azide conversion to the amide in the presence of thioacetic acid and base catalyzed deprotection of the acyl and methoxy protecting groups.…”

“…The 1,5-disubstituted product was synthesized via the so-known RuAAC approach, using Cp*RuCl(PPh 3 ) 2 as catalyst (Scheme 33). Successively, Anand et al [88] published a click chemistry-based approach for the regioselective synthesis of 1,5-coumarinyl 1,2,3triazoles 108 (Scheme 34). Even though most of the syntheses are exerted using the RuAAC approach, the use of catalytic protocols that involve other metals showed important progress.…”
