Deiana, Luca; Ghisu, Lorenza; Afewerki, Samson; Verho, Oscar; Johnston, Eric V.; Hedin, Niklas; Bacsik, Zoltan; Cordova, Armando published the artcile< Enantioselective heterogeneous synergistic catalysis for asymmetric cascade transformations>, SDS of cas: 3893-18-3, the main research area is enal alkyne asym cascade cyclization spirocyclization palladium silica catalyst; cyclopentenealdehyde asym synthesis; spiro oxindole asym synthesis.
A modular design for a novel heterogeneous synergistic catalytic system, which simultaneously activates the electrophile and nucleophile by the combined activation modes of a sep. metal and non-metal catalyst, for asym. cascade transformations on a solid surface is disclosed. This modular catalysis strategy generates carbocycles (≤97.5:2.5 er) as well as spirocyclic oxindoles (97.5:2.5 to >99:0.5 er), containing all-C quaternary centers, in a highly enantioselective fashion via a one-pot dynamic relay process.
Advanced Synthesis & Catalysis published new progress about Cyclization catalysts, stereoselective. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, SDS of cas: 3893-18-3.
