Simple Access to Isoxazole-Containing Heterocyclic Hybrids: Isoxazole/Oxazole and Isoxazole/Pyridine
Russian Journal of General Chemistry, 2023 Abstract The synthesis of substituted isoxazole–oxazole hybrids by the noncatalytic reaction of methyl 2-diazo-2-(alkyl/aryl/hetarylisoxazol-5-yl)acetates with alkyl and aryl cyanides has been reported. According to DFT calculations, the reaction proceeds through the intermediate formation of a nitrile ylide and its ...
