A generalizable procedure to C2-symmetric 2,2′-bipyridines based on two consecutive constructions of the pyridine rings is reported. As an example of this strategy the title bipyridine has been prepared in four steps from 3-benzyloxy-2-butanone and (1R,5R)-3-methylenenopinone.
报道了基于吡啶环的两个连续结构的可推广到 C2 对称 2,2'-联吡啶的程序。作为这种策略的一个例子,标题联吡啶是由 3-苄氧基-2-丁酮和 (1R,5R)-3-亚甲基蒎酮分四步制备的。
