The ring-opening of 3-aminocyclobutanone oximes enables easy generation of primary alkyl radicals, capable of undergoing an unprecedented strain-release, desulfonylative radical Truce–Smiles rearrangement, providing divergent access to valuable 1,3 diamines and unnatural β-amino acids. Characterized by mild conditions and wide scope of migrating species, this protocol allows the modular assembly of
3-氨基环丁酮肟的开环能够轻松生成伯烷基自由基,能够进行前所未有的应变释放、脱磺酰化自由基休战-微笑重排,为获得有价值的 1,3 二胺和非天然 β-氨基酸提供不同的途径。该协议的特点是条件温和,迁移物种范围广,允许在无过渡金属的室温条件下进行 sp 3 -芳基的模块化组装。
