摘要

In our earlier communications, we reported the synthesis and stereochemistry of various fused and spiro isoxazolines and pyrazolines prepared by 1,3 -dipolar cycloaddition of nitrile oxides and nitrile imines to activated olefins.1-4 View all referencesIn continuation of this work, we now describe the use of 6-carbethoxy- 3,5-diarylcyclohex-2-enone 1an intermediate with three versatile functional groups ie, ketone, olefin and ester, for the syntheses of various fused isoxazole ...
