The Ugi four-component reaction (U-4CR) was utilized to prepare divalent and trivalent cluster mannosides. Thus, two target compounds 6 and 8 were obtained efficiently using carboxymethyl 2, 3, 4, 6-tetra-O-acetyl--D-...The Ugi four-component reaction (U-4CR) was utilized to prepare divalent and trivalent cluster mannosides. Thus, two target compounds 6 and 8 were obtained efficiently using carboxymethyl 2, 3, 4, 6-tetra-O-acetyl--D-mannopyranoside 4 as acid component, and 1, 6-hexanediamine or tris(2-aminoethyl)amine as the multivalent scaffolds.展开更多
The association constant (Ka) values were calculated by the function-strengthen ing neural networks (FNN) for the inclusion complexation of α-CD with mono- and 1,4-disubstituted benzenes. The lnKa predicted by FNN fr...The association constant (Ka) values were calculated by the function-strengthen ing neural networks (FNN) for the inclusion complexation of α-CD with mono- and 1,4-disubstituted benzenes. The lnKa predicted by FNN from Rm, π and σ constants of substituents are in great agreement with the experimental data.展开更多
