NiH-catalyzed asymmetric hydroalkynylation of α,β-unsaturated amides
An enantioselective NiH-catalyzed hydroalkynylation of α,β-unsaturated amides is reported. A wide range of α,β-unsaturated amides and bromoalkynes are suitable substrates for this reaction, which proceeds under mild conditions, allowing access to a ...

Detection of atmospheric gaseous amines and amides by a high-resolution time-of-flight chemical ionization mass spectrometer with protonated ethanol reagent ions [PDF]
Amines and amides are important atmospheric organic-nitrogen compounds but high time resolution, highly sensitive, and simultaneous ambient measurements of these species are rather sparse.

Progress in Catalytic Asymmetric Reactions with 7-Azaindoline as the Directing Group
α-Substituted-7-azaindoline amides and α,β-unsaturated 7-azaindoline amides have emerged as new versatile synthons for various metal-catalyzed and organic-catalyzed asymmetric reactions, which have attracted much attention from chemists.

Amide nitrogen pyramidalization changes lactam amide spinning [PDF]
AbstractAlthough cis-trans lactam amide rotation is fundamentally important, it has been little studied, except for a report on peptide-based lactams. Here, we find a consistent relationship between the lactam amide cis/trans ratios and the rotation rates between the trans and cis lactam amides upon the lactam chain length of the stapling side-chain of
