Aldehyde O-alkyl oximes were converted into ketones with high yields when they were treated with alkyllithium compounds or Grignard reagents followed by hydrolysis. Amines as reductive alkylation products of aldehyde O-alkyl oximes were also obtained by BH3 reduction before hydrolysis.

Ni-triphos complex as the first Ni-based homogeneous catalyst for both reductive amination of carbonyl compounds with ammonia and hydrogenation of nitroarenes to prepare all kinds of primary amines. Remarkably, this Ni-complex enabled the synthesis of functionalized and structurally diverse benzylic, heterocyclic and aliphatic linear and branched primary amines as well as aromatic primary amines starting
Transformation of biomass into valuable nitrogen‐containing compounds is highly desired, yet limited success has been achieved. Here we report an efficient catalyst system, partially reduced Ru/ZrO2, which could catalyze the reductiveamination of a variety of biomass‐derived aldehydes/ketones in aqueous ammonia. With this approach, a spectrum of renewable primary amines was produced in good to excellent

Abstract Grignardreagents add to benzonitrile at low temperature catalyzed by CuBr and TBSCl affording N-TBS ketimines, which were investigated as intermediaries for the synthesis of primary amines and ketones. N-silylimines were easily obtained by an organolithium addition to benzonitrile followed by a reaction with TBSCl in CH2Cl2. In situ reduction of these imines by BH3 and 1,3,2-oxazaborolidines

This invention is in the field of medicinal chemistry. In particular, the invention relates to a new class of small-molecules having a quinazolinedione structure which function as reactive oxygen species (ROS) inducers and inhibitors of mitochondrial activity within cancer cells (e.g., pancreatic cancer cells), and their use as therapeutics for the treatment of cancer (e.g., pancreatic cancer) and other diseases.
