An Unusual Rearrangement of N,N-Dibenzyl-2-aminopropanal to N,N-Dibenzyl-1-aminopropanone.
摘要:
N,N-dibenzyl-2-aminopropanal la derived from alanine rearranges to the corresponding ketone, N,N-dibenzyl-1-aminopropanone upon exposure to either silica gel or pyridinium acetate. Similar rearrangements do not occur with aldehydes derived from phenylalinine, valine, leucine, proline or phenylglycine. One mechanistic explanation for the rearrangement is a facile 1,2-methyl shift, followed by 12-hydrogen shift. (C) 1997 Elsevier Science Ltd.

Prochiral aminoketones are key intermediates for the synthesis of optically active amino alcohols, and glycerol is one of the main biomass‐based alcohols available in industry. In this work, glycerol was catalytically activated and purposefully converted with amines to generate highly valuable prochiral aminoketones, as well as N‐formamides and N‐methyl amines, over CuNiAlOx catalyst. The catalyst structure

oxidative Umpolung reaction of silyl enol ethers utilizing simple iodide salts for the synthesis of α-amino ketones is described. The products were isolated in excellent yields of up to 100%, and various functionalized starting materials were accepted in an undivided electrochemical cell design. Moreover, a sensitivity assessment to ensure an improved reproducibility of the reaction and cyclic voltammetry

(II) based on the 2,5-pyrrolidinedione (X = CH2, succinimide) and 2,4-imidazolidinedione (X = NH, hydantoin) ring systems have been prepared. The compounds were designed on the basis of a potential interaction in the gamma-aminobutyric acid (GABA) neurotransmitter system and evaluated for anticonvulsant activity. The 3-(aminomethyl)-2,5-pyrrolidinediones were prepared by a dehydration procedure beginning
