Concise Asymmetric Synthesis of Fully Substituted Isoxazoline- N -Oxide through Lewis Base Catalyzed Nitroalkene Activation

CHEMISTRY - A EUROPEAN JOURNAL, Issue 29 2010
Cheng Zhong Dr.
Transforming isoxazoline- N -oxides: A concise asymmetric synthesis of isoxazoline- N -oxides is reported through secondary amine Lewis base catalyzed nitroalkene activation and sequential intermolecular condensation with aldehydes and ylides. Application of camphor-derived chiral sulfur ylides gave the enantiomeric-enriched isoxazoline- N -oxides in excellent yields and stereoselectivity. Simple transformations of isoxazoline- N -oxide led to the gram-scale synthesis of a (,)-clausenamide analogue in four steps, with excellent stereochemistry control (see scheme). [source]
