It all adds up: The 1,4-addition of organoboronic acids to activated alkenes catalyzed by [Co(dppe)Cl(2)] is described. A [3+2]-annulation reaction of ortho-iminoarylboronic acids with acrylates to give various aminoindane carboxylic acid derivatives with cis-stereoselectivity is also demonstrated (see scheme; dppe = 1,2-bis(diphenylphosphino)ethane).
描述了[Co(dppe)Cl(2)]催化的有机硼酸与活化烯烃的 1,4-加成。邻亚胺基芳基硼酸与丙烯酸酯的[3+2]-环化反应也证明了具有顺式立体选择性的各种氨基茚烷羧酸衍生物的生成(见方案;dppe = 1,2-双(二苯基膦基)乙烷)。
