An efficient intramolecular palladium-catalyzed, asymmetric reductive-Heck reaction has been developed, which allowed for the synthesis of either enantiomericallyenriched 3-substituted indanones or α-exo-methylene indanones depending on the base used.
A versatile procedure for the synthesis of optically pure 1-amino-3-aryl indanes is presented, exemplified by the synthesis of the triple uptake inhibitor (+)-indatraline (1).

Enantioselective synthesis of potentially useful chiral 3-aryl-1-indanones was achieved through a rhodium-catalyzedasymmetric intramolecular 1,4-addition of pinacolborane chalcone derivatives using extraordinary simple MonoPhos as chiral ligand under relatively mild conditions. This novel protocol offers an easy access to a wide variety of enantioenriched 3-aryl-1-indanone derivatives in high yields

has been achieved through the merger of iminium ion catalysis and transition-metal catalysis such that asymmetricinduction derives from a readily accessible, inexpensive chiral nonracemic secondary amine catalyst rather than a chiral nonracemic phosphine as is typical of conventional asymmetric hydroacylation methods.
An efficient synthesis of chiral 3-arylindanones via iridium-catalyzed asymmetrichydrogenation of 3-arylindenones has been developed. The reaction showed good compatibility with various functional groups, delivering a variety of 3-arylindanones in excellent yields and with good enantioselectivities. The reaction was also carried out on a gram-scale, delivering the product in quantitative yield. In
