A Pd- and norbornene-catalyzed domino procedure has been developed to synthesize indoline compounds. This reaction provides efficient access to indolines by employing aryl iodides with aziridines as new electrophiles. The transformation is scalable and tolerates a range of functional groups.

The synthesis of 2-aminophosphates is achieved by a SN2-type ringopening reaction of various N-protected or free aziridines with phosphoric acids in a regiospecific and/or enantiospecific way. A one-pot, two-step procedure is also developed enabling direct access to 2-aminophosphates from olefins without isolation of the aziridine intermediates.
通过各种N-保护的或游离的氮丙啶的S N 2型开环反应以区域特异性和/或对映体特异性的方式实现磷酸2-氨基磷酸酯的合成。还开发了一种一锅两步的方法,无需分离氮丙啶中间体即可直接从烯烃获得2-氨基磷酸酯。

A nickel-catalyzedcross-coupling reaction between N-sulfonyl aziridines and organozinc reagents is reported. The catalytic system comprises an inexpensive and air-stable Ni(II) source and dimethyl fumarate as ligand. Regioselective synthesis of β-substituted amines is possible under mild and functional-group-tolerant conditions. The stereoselectivity of the reaction is consistent with a stereoconvergent
报道了 N-磺酰基氮丙啶和有机锌试剂之间的镍催化交叉偶联反应。该催化系统包含廉价且空气稳定的 Ni(II) 源和富马酸二甲酯作为配体。β-取代胺的区域选择性合成在温和和官能团耐受的条件下是可能的。该反应的立体选择性与其中磺酰胺指导 CC 键形成的立体会聚机制一致。
Selective Cyclopropanation/Aziridination of Olefins Catalyzed by Bis(pyrazolyl)borate Cu(I) Complexes
Bis(pyrazolyl)borate Cu(I) complex catalysts with intramolecular C−H⋅⋅⋅Cu weak interaction as a “switch” have been applied in catalytic carbene/nitrenetransfer and addition to C=C bonds. The catalytic cyclopropanation/aziridination reaction demonstrates wide substrate scope, high yields, and selectivity.
