  • Enantioselective Synthesis of Dialkylated <i>N</i>-Heterocycles by Palladium-Catalyzed Allylic Alkylation
    作者:Yoshitaka Numajiri、Gonzalo Jiménez-Osés、Bo Wang、K. N. Houk、Brian M. Stoltz
    DOI:10.1021/ol503425t
    日期:2015.3.6
    The enantioselective synthesis of alpha-disubstituted N-heterocyclic carbonyl compounds has been accomplished using palladium-catalyzed allylic alkylation. These catalytic conditions enable access to various heterocycles, such as morpholinone, thiomorpholinone, oxazolidin-4-one, 1,2-oxazepan-3-one, 1,3-oxazinan-4-one, and structurally related lactams, all bearing fully substituted alpha-positions. Broad functional group tolerance was explored at the alpha-position in the morpholinone series. We demonstrate the utility of this method by performing various transformations on our useful products to readily access a number of enantioenriched compounds.
