A novel and simple asymmetric synthesis of CMI-977 (LDP-977): A potent anti-asthmatic drug lead

A practical gram scale asymmetric synthesis of CMI-977 is described. A tandem double elimination of an α-chlorooxirane and concomitant intramolecular nucleophilic substitution was used as the key step. Jacobsen hydrolytic kinetic resolution and Sharpless
