描述了一种温和的、钯 (II) 催化的烯烃成环氨基乙酰氧基化。在 PhI(OAc)2 作为氧化剂的存在下,用催化钯 (II) 处理一系列含氮亲核试剂,导致烯烃氨基乙酰氧基化,得到各种含氮杂环。我们的研究表明高水平的反应区域和立体控制的可能性。这似乎是立体选择性反式烯烃双官能化,因此是相关顺式选择性金属催化烯烃氨基羟基化过程的有用替代方法。
A facile and efficient enantioselectivebromoaminocyclization of unsaturated sulfonamides has been developed using an amino-thiocarbamate catalyst. A range of enantioenriched pyrrolidines were prepared with up to 99% yield and 99% ee. The corresponding lactams could be obtained through oxidation of the pyrrolidines.

A mild, palladium(II)-catalyzed ring-forming aminoacetoxylation of alkenes is described. Treatment of a range of nitrogennucleophiles with catalytic palladium(II) in the presence of PhI(OAc)2 as oxidant resulted in alkene aminoacetoxylation, affording a variety of nitrogen-containing heterocycles. Our studies indicate the possibility for high levels of reaction regio- and stereocontrol. It appears
