Rationale: Novel synthetic “bath salt” cathinones continue to appear on the street as abused and addictive drugs. The range of subjective experiences produced by different cathinones suggests that some compounds have primarily dopaminergic activity (possi
Regiospecific synthesis of α-diones, α,α-dialkoxyketones and α-alkoxy-α-sulfenylated ketones

A convenient synthesis of α-diones and their monoprotected acetals, i.e. α-ketoacetals, was developed by mercury induced solvolysis of regiospecifically formed α-chloro-α-(alkylthio)ketones. Analogously, α-alkoxy-α-sulfenylated ketones were formed when reacting α-chloro-α-sulfenylated ketones with an alkaline alcoholic medium, α-Alkoxy-α-sulfenylated ketones themselves could be transformed into α-diones or ?-ketoacetals, which in turn were hydrolyzed under anhydrous conditions into the corresponding α-diones.

Asymmetric Transfer Hydrogenation: Dynamic Kinetic Resolution of α-Amino Ketones
Gediya, Shweta K.,Clarkson, Guy J.,Wills, Martin
, p. 11309 - 11330 (2020/10/12)
A series of α-amino ketones were reduced using asymmetric transfer hydrogenation (ATH) through a dynamic kinetic resolution (DKR). The protecting group was matched to the reducing agent, and following optimization, a series of substrates were investigated, giving products in high diastereoselectivity, over 99% ee in several cases and full conversion. The methodology was applied to the enantioselective synthesis of an MDM2-p53 inhibitor precursor.
A metal-free aerobic oxidative bromination of anilines and aryl ketones with 2-methylpyridinium nitrate as a reusable ionic liquid

An aerobic oxidative bromination of anilines and aryl ketones catalyzed by recyclable 2-methylpyridinium nitrate ionic liquid is achieved in water using hydrobromic acid as the bromine source and molecular oxygen as the oxidant. The catalytic system shows good efficiency and atom economy.
Facile Approach to Geminal HeterodihalogenationOne-Pot Synthesis of α-Bromo-α-Chloro Ketones

An efficient and practical protocol for the geminal heterodihalogenation of methyl ketones by using readily available dimethyl sulfoxide and a combination of HCl and HBr is reported. Control experiments suggested that the acidity of the solution, as well as the oxidizing ability and nucleophilicity of the dimethyl sulfoxide might work cooperatively in ensuring the success of the tandem substitution. Its operational simplicity, easy accessibility, and mild oxidative conditions suggest that the present strategy might be useful for the assembly of bromochloromethyl functional groups in drug discovery.

Substantial advances in enantioconvergent C(sp3)-C(sp3) bond formation reactions have been made in recent years through the use of transition-metal-catalyzed cross-coupling reactions of racemic secondary alkyl electrophiles with organometallic reagents. Herein, we report a general process for the asymmetric construction of alkyl-alkyl bonds adjacent to heteroatoms, namely, a nickel-catalyzed enantioconvergent reductive hydroalkylation of olefins with α-heteroatom phosphorus or sulfur alkyl electrophiles. Including the use of readily available olefins, this reaction has considerable advantages, such as mild reaction conditions, a broad substrate scope, and good functional group compatibility, making it a desirable alternative to traditional electrophile-nucleophile cross-coupling reactions.

, p. 1398 - 1405 (2019/02/07)
Although molecular bromine (Br2) is a useful brominating reagent, it is not easy to handle. Herein, we describe the preparation of a novel air-stable bromine complex prepared from 1,3-dimethyl-2-imidazolidinone (DMI) and Br2, which was identified to be (DMI)2HBr3 by spectral and X-ray techniques. This complex was then used to brominate olefins, carbonyl compounds, and aromatics, as well as in the Hofmann rearrangement. Yields of reaction products using this complex were almost the same or superior to those using other bromine alternatives.
