Category: thiazolidine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (R)-4-(tert-Butyl)-2-(5-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole, is researched, Molecular C13H15F3N2O, CAS is 1428537-19-2, about Enantioselective total synthesis of the highly selective sphingosine-1-receptor VPC01091 by the Heck desymmetrization of a non-activated cyclopentene-fused spiro-pyrrolidinone. Author is Khan, Ismat Ullah; Kattela, Shivashankar; Hassan, Abbas; Correia, Carlos Roque Duarte.
A novel, efficient and enantioselective Heck-Matsuda desymmetrization of non-activated cyclopentene-fused spiro-pyrrolidinones was developed. The reaction provided the Heck products in good to excellent yields and selectivities and tolerated a variety of functional groups in arenediazonium tetrafluoroborates (12 examples) with respect to its electronics and substitution patterns. This methodol. was successfully applied in the concise enantioselective total synthesis of VPC01091 (I), a drug candidate for the treatment of multiple sclerosis.
