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
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

A nickel-catalyzed reductivecyclization of enones affords a wide array of indanones in high enantiomeric induction. The reaction is featured with an unprecedented broad scope of substrates. The versatility of the new method is demonstrated in several short stereoselective syntheses of medically valuable (R)-tolterodine, parent and deuterated (+)-indatraline, and an antitumor natural product, (+)-multisianthol
