  A Practical Enantioselective Synthesis of Odanacatib, a Potent Cathepsin K Inhibitor, via Triflate Displacement of an α-Trifluoromethylbenzyl Triflate

  摘要：

  An enantioselective synthesis of the Cathepsin K inhibitor odanacatib (MK-0822) 1 is described. The key step involves the novel stereospecific S(N)2 triflate displacement of a chiral alpha-trifluoromethylbenzyl triflate 9a with (S)-gamma-fluoroleucine ethyl ester 3 to generate the required alpha-trifluoromethylbenzyl amino stereocenter. ne triflate displacement is achieved in high yield (95%) and minimal loss of stereochemistry. The overall synthesis of I is completed in 6 steps in 61% overall yield.

  The application provides a photochemical process for the chemoselective fluorination of an organic compound by combining a carbon-containing compound having an unactivated sp3 C-H bond with a reagent system comprised of a fluorinating agent, and a photocatalyst, in the presence of a light source. Provided as fluorinating agent is N-fluorobenzenesulfonimide (NFSI) or 1-chloromethy1-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Selectfluor™), as photocatalyst is tetrabutylammonium decatungstate (TBADT), and as light source is a 365 nm UV lamp. The reactions conditions result in the C-H bond being replaced by a C-F bond, to provide a fluorinated carbon-containing compound.
