This study describes a cascade method for the synthesis of β-aminoketones through the reductive hydroamination of alkynes under very mild metal-free conditions. It allows for the rapid conversion of ynones and amines into corresponding β-aminoketones with a broad substrate scope and diverse functionalities. This straightforward and easy-to-handle reaction process can be successfully applied for the synthesis of Proroxan and Propipocaine, offering a potential option for the synthesis of drug molecules with the β-aminoketone skeleton.

The first copper-catalyzed direct β-functionalization of saturated ketones is reported. This protocol enables diverse ketones to couple with a wide range of nitrogen, oxygen and carbon nucleophiles in generally good yields under operationally simple conditions. The detailed mechanistic studies including kinetic studies, KIE measurements, identification of reaction intermediates, EPR and UV-visible experiments were conducted, which reveal that this reaction proceeds via a novel radical-based dehydrogenation to enone and subsequent conjugate addition sequence.

The synthesized compounds have been characterized and screened against ITCC 5226 Sclerotium rolfsii and ITCC 0482 Macrophomina phaseolina and MTCC739 Escherichia coli, ATCC6533 Bacillus subtilis, ATCC9144 Staphylococcus aureus, ATCC25619 Pseudomonas aeruginosa and ATCC24433 Candida albicans.
Asymmetric hydrogenation of β-amino ketones with the bimetallic complex RuPHOX-Ru as the chiral catalyst

supporting information, p. 3855 - 3861 (2014/03/21)
Asymmetric hydrogenations of a series of β-amino ketones were carried out with a bimetallic complex (RuPHOX-Ru) as the chiral catalyst. Almost all the reactions (performed in a mixed solvent system of toluene and H2O in the presence of KOH) gave quantitative conversions into their respective products with up to 99.9% ee. The RuPHOX-Ru catalyst is stable to both moisture and air. The procedure has the benefits of being inexpensive, environmentally friendly and highly efficient. Under a relatively low catalyst loading (TON = 2000), key intermediates of fluoxetine, tomoxetine and nisoxetine could be obtained in quantitative yield and in up to 99.9% ee. This methodology represents a promising alternative to the synthesis of the aforementioned drugs and their analogues. This journal is The Royal Society of Chemistry 2013.

Substituted aryloxypropanolamines (6-20) were synthesized and evaluated for their anorexigenic activity. Among them 4-cyanoaryloxy (7), 2-methylaryloxy (9), 2-methoxyl aryloxy (10), 4-acetamidoaryloxy (15), 4-bromoaryloxy (16) and 4-ethylaminoaryloxy (20) exhibited potent anorexigenic activity. According to QSAR studies, the electronic parameter 'σ' plays an important role in describing the variance in activity. Birkhaeuser Boston 2004.
