The Acceleration of the Rearrangement of α-Hydroxy Aldimines by Lewis or Bronsted Acids
Zhang, Xin,Dai, Yijing,Wulff, William D.
, p. 2015 - 2018 (2018)
An efficient method was developed for the synthesis of α-amino ketones from α-hydroxy imines. The reaction occurs through an α-iminol rearrangement involving the migration of a substituent of the carbinol carbon to the imine carbon. The optimal catalysts were found to be silica gel or montmorillonite K 10, which effected migration of a variety of aryl and alkyl substituents in high yields. The rearrangement can also be carried out on imines generated in situ from aldehydes and amines in essentially the same yields as those from the preformed imines.
Chemoselective reduction of α-imino carbonyl compounds into α-amino carbonyl compounds with titanium tetraiodide
Shimizu, Makoto,Sahara, Tetsuya,Hayakawa, Ryuuichirou
, p. 792 - 793 (2001)
α-Imino carbonyl compounds are chemoselectively reduced with titanium tetraiodide to give α-amino carbonyl compounds in good to excellent yields.
Visible-Light-Induced Radical Acylation of Imines with α-Ketoacids Enabled by Electron-Donor-Acceptor Complexes
Zhang, Hong-Hao,Yu, Shouyun
, p. 3711 - 3715 (2019/05/24)
A visible-light-induced radical acylation of imines with α-ketoacids has been achieved, enabled by an electron-donor-acceptor (EDA) complex. This EDA complex-mediated process eradicates the use of a photocatalyst. Visible light is used as the sole promote
Br?nsted Base-Catalyzed Reductive Cyclization of Alkynyl α-Iminoesters through Auto-Tandem Catalysis
Kondoh, Azusa,Terada, Masahiro
supporting information, p. 5309 - 5313 (2018/09/13)
A novel reductive cyclization of alkynyl α-iminoesters was developed through auto-tandem catalysis with a Br?nsted base as the catalyst. The reaction system involves two mechanistically different elementary processes, both of which are efficiently catalyz
