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 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
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).

A world of possibilities: Gold‐catalyzed reactions of 2‐ethynylbenzyl ethers with organicoxides and α‐diazoesters gave 1,3‐dihydroisobenzofuran and naphthalene derivatives, respectively (see scheme; EWG=electron‐withdrawing group). Mechanisms for the formation of the formal cycloadducts were elucidated by isotope labeling.
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
