实验步骤: After Boc deprotection of the Fmoc-Lys(Boc)-OH, Fmoc-Lys-OH was obtained (FIG. 23, (1)). The furan moiety was coupled to the ε-amine of Fmoc-Lys-OH by ureum formation with furfuryl isocyanate to obtain 2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-6-(3-(furan-2-ylmethyl)ureido)hexanoic acid (FIG. 23, (2)), or by amide formation with pentafluorophenyl-furan-2-carboxylate (FIG. 23, (4)) to obtain 2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-6-(furan-2-carboxamido)hexanoic acid (FIG. 23, (5)). The synthesis was finished with Fmoc deprotection, yielding the amphiphilic products (3) or (6) (FIG. 23) as a white powder. Hence, the furan amino acid of Formula (XId) or the furan amino acid of Formula (XIc) was obtained (FIG. 23, (3) or (6) respectively).
