Bioorg Med Chem Lett. 2006 Jun 15;16(12):3205-8. doi: 10.1016/j.bmcl.2006.03.051. Epub 2006 Apr 17.

Abstract

The synthesis of the major metabolite of a potent 3-aminopyrazole CDK2/cyclin A inhibitor is presented. A stereoconservative approach starting from malic acid was employed to construct the hydroxy-substituted pyrrolidinone moiety. In the key step of the synthesis the use of cyanoborohydride immobilized on Amberlyst 26 in trifluoroethanol represented a valid alternative to conventional solution-phase reducing agents.
