The synthesis of 1-pyrrolinesfrom cyclobutanol derivatives and an aminating reagent (MsONH3OTf) has been developed. This one-pot procedure achieves C–N bond/C═N bond formation via ring expansion. A series of 1-pyrroline derivatives are synthesized in moderate to good yields under mild conditions.
termination reaction, which includes two β-carbon elimination processes. This tandem reaction features mild conditions, high yields, good functional group tolerance, and a broad substrate scope. Meanwhile, four types of electrophiles (N-benzoyloxyamines, alkyl iodides, aryl bromides, and benzylchlorides) are quite compatible with this termination reaction for the construction of various types of polysubstituted

4-palladium migration/ring-opening C–C cleavage cascade, giving trisubstituted alkenes in high yields. The protocol features good regioselectivity, high yields, broad substrate scopes, and good functional group tolerance. The mechanistic studies implicate that the cross-coupling reaction occurs via oxidative addition, 1,4-palladium migration, ring-opening C–C cleavage, and reductive elimination. DFT calculations
which allows functionalization to occur exclusively at the β-position of ketones. The substrate scope includes a wide range of cycloalkanols as well as diverse N, O, C, and P-centered nucleophiles, providing ready access to β-functionalized ketones as products. Mechanistic studies support the generation of α,β-unsaturated ketones as key intermediates followed by Michael addition with nucleophiles.
已经研究了环烷醇与亲核试剂的电化学解构官能化,这使得官能化只发生在酮的β-位。底物范围包括范围广泛的环烷醇以及各种以 N、O、C 和 P 为中心的亲核试剂,可方便地使用 β-官能化酮作为产品。机理研究支持生成 α,β-不饱和酮作为关键中间体,然后与亲核试剂进行迈克尔加成。
