Verma, Ram Subhawan; Khatana, Anil Kumar; Mishra, Monika; Kumar, Shailesh; Tiwari, Bhoopendra published the artcile< Access to enantioenriched 4-phosphorylated δ-lactones from β-phosphorylenones and enals via carbene organocatalysis>, Recommanded Product: 3-(4-Bromophenyl)acrylaldehyde, the main research area is carbene catalyzed cycloaddition reaction phosphorylenone enal; enantioenriched phosphorylated gamma lactone preparation crystal structure reactivity; crystal structure enantioenriched phosphorylated gamma lactone; mol structure enantioenriched phosphorylated gamma lactone.
N-heterocyclic carbene (NHC) catalyzed direct access to enantioenriched 4-phosphorylated δ-lactones from β-phosphorylenones and enals was achieved. The sterically demanding β-phosphonate-substituted enones, having competing regiomeric reaction centers, have remained elusive so far in intermol. cycloaddition reactions under NHC catalysis. All the products were obtained in excellent yield and enantioselectivity. These phosphorylated δ-lactones could be transformed into challenging multi-functionalized chiral esters and amides loaded with a β-ketophosphonate functionality.
