New total syntheses of orelline and some analogues are reported. The methodology involves metalation of 3-alkoxy-2-iodopyridines to afford 3,4-dialkoxy-2-iodopyridines, on which cross-coupling reactions are performed to reach the 2,2′-bipyridine skeleton of the alkaloid.
据报道,新合成的Orelline和一些类似物。该方法包括将3-烷氧基-2-碘吡啶金属化以提供3,4-二烷氧基-2-碘吡啶,在其上进行交叉偶联反应以达到生物碱的2,2'-联吡啶骨架。
