概要

4-p-Chlorophenyl-3,5-bis (methoxycarbonyl) isoxazoline-1-oxide reacted with excess titanium tetrachloride in dichloromethane to yield a novel fused heterocycle, dimethyl 7-chloro-3a, 4-dihydro-5aH-benzofuro-[3,3a-d] isoxazole-3,4-dicarboxylate in good yield. The result of this structural determination by single crystal X-ray analysis is reported.
