摘要

本研究提出了一种串联钯催化碳醚化合成螺-异恶唑啉的有效方法。利用环烷基系链肟和芳基/烯基溴，该方案能够构建广泛的具有不同官能团的新型螺-异恶唑啉化合物。此外，我们还研究了该串联反应的不对称版本，其中使用手性叔丁烷磺酰胺单膦配体获得了良好的化学产率和优异的对映选择性。

Access to spiro-isoxazoline via a palladium-catalyzed carboetheri-fication of cycloalkenyl-tethered oximes

This study presents an efficient method for synthesizing spiro-isoxazolines through a tandem palladium-catalyzed carboetherification approach. Utilizing cycloalkenyl-tethered oximes and aryl/alkenyl bromides, this protocol enables the construction of a wide range of novel spiro-isoxazoline compounds bearing diverse functional groups. Furthermore, we also investigated the asymmetric version of this tandem reaction, where the use of a chiral tert-butanesulfinamide monophosphine ligand achieved good chemical yield and excellent enantioselectivity.
