Zhang, Chun; Tutkowski, Brandon; DeLuca, Ryan J.; Joyce, Leo A.; Wiest, Olaf; Sigman, Matthew S. published the artcile< Palladium-catalyzed enantioselective Heck alkenylation of trisubstituted allylic alkenols: a redox-relay strategy to construct vicinal stereocenters>, Safety of (R)-4-(tert-Butyl)-2-(5-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole, the main research area is alkenyl aldehyde ketone preparation enantioselective diastereoselective; allylic alkenol alkenyl triflate redox relay Heck palladium catalyst.
An enantioselective, redox-relay Heck alkenylation of trisubstituted allylic alkenol substrates with alkenyl triflates was developed to afford alkenyl aldehydes/ketones e.g., I. This process enabled the construction of vicinal stereocenters in high diastereo- and enantioselectivity and allowed the formation of enolizable α-carbonyl methyl-substituted stereocenters with no observed epimerization under the reported reaction conditions.
Chemical Science published new progress about Alkenals Role: SPN (Synthetic Preparation), PREP (Preparation). 1428537-19-2 belongs to class pyridine-derivatives, and the molecular formula is C13H15F3N2O, Safety of (R)-4-(tert-Butyl)-2-(5-(trifluoromethyl)pyridin-2-yl)-4,5-dihydrooxazole.
