TITLE OF THE INVENTION STEREOSELECTIVE SYNTHESIS OF LEUKOTRIENE ANTAGONISTS ABSTRACT OF THE INVENTION The present invention relates to a stereo- selective synthesis of leukotriene antagonists. More particularly, this invention relates to the stereo- selective synthesis of (BS,.gamma.R) and (BR,.gamma.S)- 4-((3-(4-acetyl-3-hydroxy-2-propyl(phenoxy)propyl)- thio)-.gamma.-hydroxy-.beta.-methylbenzenebutanoic acid, and related compounds. These compounds are useful therapeutic agents for treating allergic conditions, asthma, cardiovascular disorders, inflammation and pain in mammals, especially humans.
