合成路线1
该中间体在本合成路线中的序号：(VI)Phenacyl ester (III) was prepared by treatment of the cesium salt of N-Boc-tryptophan (I) with 2-bromoacetophenone (II) in DMF. Cyclization of keto ester (III) with ammonium acetate in refluxing xylene yielded the target imidazole (IV). Acidic Boc group deprotection of (IV) then gave amine (V). Finally, Pictet-Spengler cyclization of (V) with 6-undecanone (VI) provided the desired tetrahydrocarboline.
