Molecules with a peptide link in protostellar shocks: a comprehensive study of L1157 [PDF]

open access: yes, 2014
Interstellar molecules with a peptide link -NH-C(=O)-, like formamide (NH$_2$CHO), acetamide (NH$_2$COCH$_3$) and isocyanic acid (HNCO) are particularly interesting for their potential role in pre-biotic chemistry.

2-[2-Methyl-5-phenyl-1-(3,4,5-trimethoxyphenyl)-1H-pyrrol-3-yl]-2-oxo-N-(pyridin-4-yl) acetamide

open access: yesMolbank, 2018
We synthesized 2-[2-methyl-5-phenyl-1-(3,4,5-trimethoxyphenyl)-1H-pyrrol-3-yl]-2-oxo-N-(pyridin-4-yl) acetamide 4 as a novel compound derived from the indibulin and combretastatin scaffolds, which are known anti-mitotic agents, using a multistep reaction.

Alachlor oxidation by the filamentous fungus Paecilomyces marquandii [PDF]

open access: yes, 2013
Alachlor, a popular chloroacetanilide herbicide, can be a potential health risk factor. Soil microorganisms are primarily responsible for conversion and migration of alachlor in natural environment, but knowledge concerning alachlor biodegradation is not

N-(4-Isopropoxyphenyl)acetamide [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
In the mol-ecule of the title compound, C(11)H(15)NO(2), the planar acetamide unit [maximum deviation of 0.0014 (6) Å] is oriented at a dihedral angle of 19.68 (4)° with respect to the aromatic ring. An intra-molecular C-H⋯O inter-action results in the formation of a six-membered ring. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link
