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.

, p. o304-o306 (2006)
The title compounds, C20H16ClNO and C 21H19NO2, adopt syn orientations of the C=O and N - H bonds but, like their analogues, form no strong intermolecular hydrogen bonds.
Chemoselective reduction of α-imino carbonyl compounds into α-amino carbonyl compounds with titanium tetraiodide

We present herein an unprecedented diastereoconvergent synthesis of vicinal diamines from diols through an economical, redox-neutral process. Under cooperative ruthenium and Lewis acid catalysis, readily available anilines and 1,2-diols (as a mixture of diastereomers) couple to forge two C?N bonds in an efficient and diastereoselective fashion. By identifying an effective chiral iridium/phosphoric acid co-catalyzed procedure, the first enantioconvergent double amination of racemic 1,2-diols has also been achieved, resulting in a practical access to highly valuable enantioenriched vicinal diamines.
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
Synthesis and lung cancer cell line study of pyrrolo[2,3-d]pyrimidine analogs
Dholakia, Sandip P.,Kanada, Kaushik B.,Sureja, Dipen K.,Patel, Jitendra S.
, p. 367 - 372 (2020/01/03)
Three series of new pyrrolo[2,3-d]pyrimidines having diverse groups at position C4 and N7 of the pyrrolo[2,3-d]pyrimidine core were synthesized and their cell line study on the National Cancer Institute (NCI) H1 299 lung cancer cell line was performed. The details of the synthetic methods and characterization data of the synthesized compounds have been presented in this study. Compounds 08a, 08h, 08j, 09h, 09i, 09j, 09m, 09n, and 09o showed excellent anticancer activity compared to standard doxorubicin half maximal inhibitory concentration value on NCI H1 299 (lung cancer cell line) which was nontoxic to normal Vero cell line.
