Synthesis of o-dimethylene isoxazole via isoxazole-fused 3-sulfolene
摘要:
Isoxazole-fused 3-sulfolene 12 has been synthesized from the readily available starting material 7 in three steps. Heating compound 12 at 160-180-degrees-C generates o-dimethylene isoxazole 6b which undergoes smooth cycloaddition reactions.
