, (2019/05/22)
An effective nickel-catalyzed cross-coupling of Umpolung carbonyls and alkyl halides was developed. Complementary to classical alkylation techniques, this reaction utilizes Umpolung carbonyls as the environmentally benign alkyl nucleophiles, providing an efficient and selective catalytic alternative to the traditional use of highly reactive alkyl organometallic reagents.

A simple, efficient and mild method for the selective bromination of activated aromatic compounds using ammonium bromide as the source of bromine and Oxone as the oxidant in methanol or water as solvent is reported. The reaction proceeds at ambient temperature in yields ranging from moderate to excellent without a catalyst. Georg Thieme Verlag Stuttgart.
Highly selective palladium-catalyzed oxidative Csp2-Csp 3 cross-coupling of arylzinc and alkylindium reagents through double transmetallation
Jin, Liqun,Zhao, Yingsheng,Zhu, Lizheng,Zhang, Heng,Lei, Aiwen
supporting information; experimental part, p. 630 - 634 (2009/11/30)
Using desyl chloride (2-chloro-1,2-diphenylethanone) as the oxidant, the palladium-catalyzed reaction of arylzinc with alkylindium reagents occurred smoothly in a highly selective manner to afford the products in 57-90% yields. Preliminary kinetic data in
Efficient syntheses of optically active 2-arylalkanoic acids
Beaulieu, Christian,Spino, Claude
, p. 1637 - 1640 (2007/10/03)
A highly enantioselective synthesis of 2-axylpropanoic acid was achieved, using a new developed methodology of cuprate addition to chiral carbonates derived from menthone.
Thiophenesulfonamides as endothelin receptor antagonists
Raju,Wu, Chengde,Kois, Adam,Verner, Erik,Okun, Ilya,Stavros, Fiona,Chan, Ming Fai
, p. 2651 - 2656 (2007/10/03)
The synthesis and in vitro binding affinities of a series of thiophenesulfonamides as ET(A) selective endothelin receptor antagonists is described. The most potent inhibitor displayed an IC50 of 43 nM and 3 μM to ET(A) and ET(B) receptors, respectively.
