Synthetic Route of 39648-67-4, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 39648-67-4, C20H13O4P. A document type is Article, introducing its new discovery.
A Pd-catalyzed formal [5 + 3] intermolecular cycloaddition reaction of isatin-derived alpha-(trifluoromethyl)imines with aryl substituted vinylethylene carbonates (VECs) has been reported, affording trifluoromethyl-group-containing spirooxindoles fused with an eight-membered ring as a single diastereoisomer in good yields in the presence of a Br°nsted acid in a one-pot manner under mild conditions. The asymmetric version of this reaction has been also realized using a chiral phosphine ligand along with the further transformation of the obtained product to give a spirooxindolo pyrrolidine derivative upon oxidation.
