The present invention discloses substituted diphenyloxiranes and process for synthesis thereof. The present invention also provides a process for production of enantiomerically pure anti-3,3'-diphenylmethyloxirane and anti-3,3'-diphenylpropan- 1,2-diol from racemic anti-3,3'-diphenylmethyloxirane using hydrolytic kinetic resolution. Further it provides a process for preparation of enantioselective (+)- Sertraline from anti-3,3'-diphenylpropan-1,2-diol.

Abstractmagnified imageAn efficient and stereoselective protocol for the preparation of β,β‐disubstituted acrylates in good to high yields by means of a Heck–Matsuda arylation was accomplished. The method employs a base‐ and ligand‐free Heck arylation reaction of methyl cinnamate using both electron‐deficient and electron‐rich arenediazonium salts as electrophiles. The Heck reaction displays a remarkable electronic dependence regarding the diastereoselectivity of the arylation process, which correlates with the electronic nature of the arenediazonium salts employed. A rationale for the observed diastereoselectivity is presented. The overall methodology provides a convenient route to 3‐arylindanones and 4‐aryltetralones allowing the concise formal total syntheses of the therapeutically important psychoactive compounds (±)‐indatraline and (±)‐sertraline.

The Co(III)(salen)OAc-catalyzed two stereocentered hydrolytic kinetic resolution (HKR) of anti-β,β′-diphenylmethyloxirane and anti-3-phenylethyloxiranes affords the corresponding anti-1,2-diols and oxiranes in high enantiomeric excess. The synthetic potential of this methodology is demonstrated by the enantioselective synthesis of (+)-sertraline, an antidepressant drug, and (+)-naproxen, an anti-inflammatory
Co (III)(salen)OAc催化的抗-β,β'-二苯基甲基环氧乙烷和抗-3-苯基乙基环氧乙烷的两个立体中心水解动力学拆分(HKR)提供了高对映体过量的相应的抗-1,2-二醇和环氧乙烷。该方法的合成潜力通过抗抑郁药(+)-舍曲林和抗炎药(+)-萘普生的对映选择性合成得到证明。
