Asymmetric catalytic aza-Morita–Baylis–Hillman reaction for the synthesis of 3-substituted-3-aminooxindoles with chiral quaternary carbon centers

Abstract: Asymmetric catalytic aza-Morita-Baylis-Hillman (aza-MBH) reaction of isatin-derived ketimines with MVK has been established by using chiral amino and phosphino catalysts. The reaction resulted in biomedically important 3-substituted 3-amino-2-oxindoles in good yields (>80% for most cases) and excellent enantioselectivity (90–99%ee). Twenty-eight cases assembled with chiral quaternary stereogenic centers have been examined under convenient systems.

“…Min Shi et al have developed a highly enantioselective aza-Morita-Baylis-Hillman reaction of isatin imines (1) with methyl vinyl ketones (MVK) 2 catalyzed by β-isocupreidine I and chiral phosphines II (Scheme 75 1). 8 Similar results were obtained affording 3-amino-2-oxindoles 3 bearing a C-3 tetra-substituted stereogenic centre with excellent enantioselectivity (up to 99% ee) and excellent yield up to 98%. In addition to this, the absolute configuration was also found to be same (R) in both cases.…”

“…The resulting chiral 3-amino-oxindole derivatives were obtained in good to excellent enantioselectivities and overall good yields. It was also noticed that the reaction required a shorter period (48 h), than when compared to the b-isocupreidine organocatalysts (72 h) (Scheme 67 a)) [202]. A similar approach was studied by Zhao et al, but using different acrylates as substrates and a phosphinesquaramide-derived organocatalyst C54.…”
