合成路线1
该中间体在本合成路线中的序号：(XXII)Benzoylation of furfurylamine (XXI) under Schotten-Baumann conditions provided amide (XXII). The dimethoxy dihydrofuran derivative (XXIII) was then obtained as different diastereomeric mixtures by either the electrolysis of N-benzoylfurfurylamine (XXII) in the presence of NH4Cl in MeOH or by the bromination of (XXII) in MeOH. Oxidative cleavage of (XXIII) using the Jones reagent led to 5-benzamido-4-oxo-2-pentenoic acid (XXIV), which was further hydrogenated to the pentanoic analogue (XXV). Alternatively, (XXV) was also obtained by first hydrogenation of (XXIII) to the tetrahydrofuran (XXVI), which was then subjected to Jones oxidation. Finally, acidic hydrolysis of delta-benzamido levulinic acid (XXV) provided the title compound.
