Enantioselective allylation of ketones catalyzed by N,N'-dioxide and indium(III) complex.

Xin Zhang et al.

The Journal of organic chemistry, 72(14), 5227-5233 (2007-06-15)

Complexes of (S)-pipecolic acid-, L-proline-, and other amino acid-derived N,N'-dioxides coordinated with different metal ions have been investigated in the enantioselective allylation of ketones. A variety of aromatic ketones were found to be suitable substrates in the presence of the

Catalytic enantioselective ene-type reactions of vinylogous hydrazone: construction of α-methylene-γ-butyrolactone derivatives.

Hang Zhang et al.

Chemical communications (Cambridge, England), 54(88), 12511-12514 (2018-10-23)

The catalytic asymmetric ene-type reactions of vinylogous hydrazone were accomplished by using chiral N,N'-dioxide-metal salt complexes as catalysts. A wide range of electrophiles, including isatins, α-ketoester, imines, and aldehydes reacted with (E)-2-methyl-N-(piperidin-1-yl)prop-2-en-1-imine efficiently, affording the corresponding homoallylic alcohols and amines

Asymmetric dearomatization of indoles through a Michael/Friedel-Crafts-type cascade to construct polycyclic spiroindolines.

Xiaohu Zhao et al.

Angewandte Chemie (International ed. in English), 54(13), 4032-4035 (2015-02-05)

A highly efficient asymmetric dearomatization of indoles was realized through a cascade reaction between 2-isocyanoethylindole and alkylidene malonates catalyzed by a chiral N,N'-dioxide/Mg(II) catalyst. Fused polycyclic indolines containing three stereocenters were afforded in good yields with excellent diastereo- and enantioselectivities
