diversity-oriented organic synthesis was subjected to a further test, this time in the phenol series. The model compounds selected were 2,3,6-trifluorophenol, the three isomers of (trifluoromethoxy)phenol and the three isomers of chlorophenol. A combination of optionally site selective metalations and protective group-controlled metalations enabled the selective generation of several isomeric intermediates in
面向多样性的有机合成的有机金属方法经受了进一步的测试,这次是在苯酚系列中进行的。选择的模型化合物是2,3,6-三氟苯酚,(三氟甲氧基)苯酚的三个异构体和氯苯酚的三个异构体。任选地选择性金属化和保护基团控制的金属化的组合能够在每种情况下选择性生成几种异构中间体,并随后将其转化为官能化衍生物,特别是羟基苯甲酸。
