Regioselective synthesis and side-chain metallation and elaboration of 3-aryl-5-alkylisoxazoles

Di Nunno, Leonardo,Scilimati, Antonio,Vitale, Paola

, p. 2659 - 2665 (2002)

A number of 3-aryl-5-alkylisoxazoles have been synthesized in high yields by reacting arylnitrile oxides with free enolate ions regioselectively obtained by metallation of various alkyl methyl ketones with LDA in THF at -78°C followed by dehydration. Inve
