Abstract
The 1,3-dipolar cycloaddition of 3-nitro-2(1H)-quinolones with ester-stabilized azomethine ylides derived from sarcosine ester and various aromatic aldehydes has been investigated. The structure and stereochemistry of cycloadducts were studied in detail by X-ray and NMR spectroscopy methods.
