The first synthesis of (±)-harzianopyridone, an antifungal metabolite of Trichoderma harzianum, has been achieved by metalation of 6-substituted-2,3-dimethoxy-4-pyridyl-N,N-diisopropylcarbamates. Moreover, the chosen strategy allowed the preparation of harzianopyridone analogs, by varying the groups at C-4, C-5 and C-6 on the pyridine ring.
(±)-harzianopyridone,哈茨木霉的一种抗真菌代谢产物,是通过6-取代-2,3-dimethoxy-4-pyridyl- N,N -diisopropylcarbamates的金属化而合成的。而且,通过改变吡啶环上C-4,C-5和C-6的基团,所选择的策略允许制备harzianopyridone类似物。
