Abstract Indane has been recognized as an important structural motif in organic synthesis and medicinal chemistry. Particularly, 1-aminoindanes have attracted considerable attention by virtue of their interesting biological properties, such as anti-inflammatory, analgesic, antipyretic, anticonvulsant, anti-leukemic, anti-Parkinson and etc. Therefore, a range of 1-aminoindane derivatives have been synthesized and evaluated for their clinical applications. In this context, imine directing groups have been widely used for new C−C bond formation reactions with various unsaturates such as alkenes, alkynes, and allenes. Additionally, Re(I) and Ru(II) catalysts were also employed in C−H functionalization of ketimines with alkynes and allenes to deliver the corresponding 1-aminoindenes and 1-aminoindanes, respectively. Moreover, Nishimura disclosed the Ir(I)-catalyzed stereoselective annulation of cyclic N-sulfonyl and N-acyl ketimines with 1,3-dienes to yield spiroaminoindane derivatives. Despite of great progress on the coupling reaction between imines and π-unsaturates, examples of annulation reaction using internal alkenes with high diastereoselectivity are still unexplored. In continuation of our recent works on the catalytic sp2 and sp3 C−H functionalizations using internal olefins including maleimides, we herein describe the Rh(III)-catalyzed diastereoselective formation of 1-aminoindanes using N-sulfonyl aldimines and various olefins.
