合成路线1
该中间体在本合成路线中的序号：(XXVI)A more effective preparation of (XXII) was further developed starting from N-methyltryptophan (XXIII). Protection as the N-Fmoc derivative (XXIV) and then esterification with (trimethylsilyl)diazomethane yielded (XXV). Reduction of (XXV) with triethylsilane and TFA produced indoline (XXVI), which was reoxidized to the corresponding N-hydroxyindole with Na2WO4 and H2O2, and then O-methylated with Me2SO4 to give (XXVII). Finally, Fmoc deprotection of (XXVII) with Et2NH provided aminoester (XXII).
