Jiang, Kun; Tiwari, Bhoopendra; Chi, Yonggui Robin published the artcile< Access to Spirocyclic Oxindoles via N-Heterocyclic Carbene-Catalyzed Reactions of Enals and Oxindole-Derived α,β-Unsaturated Imines>, Reference of 3893-18-3, the main research area is unsaturated imine enal NHC stereoselective spirocyclization catalyst; beta lactam fused spirocyclic oxindole stereoselective preparation.
A diastereoselective access to β-lactam fused spirocyclic oxindoles, e.g., I and II, and related compounds bearing all carbon spiro centers is described. This N-heterocyclic carbene-catalyzed process employed challenging β,β-disubstituted α,β-unsaturated imines to react with enals.
Organic Letters published new progress about Diastereoselective synthesis. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Reference of 3893-18-3.
