NiH-catalyzed asymmetric hydroalkynylation of α,β-unsaturated amides

open access: yesGreen Synthesis and Catalysis, 2022
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]

open access: yesAtmospheric Chemistry and Physics, 2016
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.

Amide nitrogen pyramidalization changes lactam amide spinning [PDF]

open access: yesNature Communications, 2019
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

An amide cyclophane [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2014
The title compound, 8,18-dithia-2,6-diaza-13(1,4)-piperidina-1(1,2),4(1,3),7(1,2)-tribenzenaoctadecaphane-10,15-diyne-3,6-dione, C32H30N4O2S2, is composed of a relatively planar bis(2-mercaptophenyl)isophthalamide unit linked to a bridging 1,4-di(but-2-yn-1-yl)piperazine unit, forming a macrocycle.

Novel endogenous N-acyl amides activate TRPV1-4 receptors, BV-2 microglia, and are regulated in brain in an acute model of inflammation

open access: yesFrontiers in Cellular Neuroscience, 2014
A family of endogenous lipids, structurally analogous to the endogenous cannabinoid, N-arachidonoyl ethanolamine (Anandamide), and called N-acyl amides have emerged as a family of biologically active compounds at TRP receptors.
