Highly diastereoselective condensation of α-nitro-esters with aldehydes catalyzed by zinc complexes of amino acids

Chatterjee,Jha,Joshi

, p. 5287 - 5289 (2007/10/03)

Zinc complexes of amino acids efficiently catalyze the condensation between α-nitro-esters and a variety of aldehydes. An unusual domino reaction sequence leads to the diastereoselective formation of substituted isoxazoline N-oxides in high yields.
