A Full Regioselective and Stereoselective Synthesis of 4‐Nitroisoxazolidines via Stepwise [3 + 2] Cycloaddition Reactions between (Z)‐C‐(9‐Anthryl)‐N‐arylnitrones and (E)‐3,3,3‐Trichloro‐1‐nitroprop‐1‐ene: Comprehensive Experimental and Theoretical Study

In the contrast to all known [3 + 2] cycloadditions between nitrones and conjugated nitroalkenes, reactions of (E)‐3,3,3‐trichloro‐1‐nitroprop‐1‐ene with (Z)‐C‐(9‐anthryl)‐N‐arylnitrones are proceeding in a fully regioselective and stereoselective manner. Additionally, density functional theory calculations suggest stepwise, zwitterionic mechanism of these cycloadditions.
