We report here a new, atom economical annulation to 2,1-benzisoxazole scaffolds via the BF3·Et2O-catalyzed reaction of glyoxylate esters and nitrosoarenes. The developed method represents a convergent route to this compound class from previously unexplored inputs and provides a range of 2,1-benzisoxazoles in moderate to high yields under convenient conditions. Along with exploration of substrate scope
我们在这里报告了一种新的、通过乙醛酸酯和亚硝基芳烃的 BF 3 ·Et 2 O 催化反应形成 2,1-苯并异恶唑支架的原子经济环化。所开发的方法代表了从以前未探索的输入中合成此类化合物的收敛途径,并在方便的条件下以中等到高产率提供了一系列 2,1-苯并异恶唑。除了底物范围的探索之外,通过18 O 标记和反应中间体的合成进行的初步机理研究为乙醛酸盐以高 O 选择性向亚硝基苯进行不寻常的翻转加成,随后进行新型弗里德尔-克来福特环化提供了证据。

Chlorobenzenes activated by a single nitro group in the ortho position undergo smooth nucleophilic substitution by the potassium salts of ethyl cyanoacetate and ethyl malonate in tert.-butanol as solvent. The 2-nitrophenyl malonic ester derivates (2a) and (2b) so obtained are easily converted into 2-nitrophenyl acetic acid and derivatives of oxindole and indole respectively.
