抄録
A solution-phase total synthesis of argifin using 3,4,5-tris(octadecyloxy)benzyl (TAGa) tag as a hydrophobic protective group of carboxylic acid was developed in 44% overall yield for 16 linear steps. Because a novel class of natural product chitinase inhibitor, argifin, was a highly water-soluble cyclic pentapeptide, solid-phase synthesis techniques can only be acceptable to conveniently prepare argifin and its derivatives. TAGa alcohol (HO-TAGa) and its esters were highly crystalline materials and favorable to dissolve into less-polar solvents such as dichloromethane, benzene, THF etc., but insolvable into polar solvents such as methanol and DMSO. The combination of HO-TAGa and Fmoc-based peptide synthesis with simple purification by the mainly recrystallization from MeOH solution furnished an efficient and practical route of argifin in the solution-phase.
