2-[(E)-(Morpholin-4-ylimino)methyl]-6-(morpholin-4-ylmethyl)phenol [PDF]
Acta Crystallographica Section E Structure Reports Online, 2013 The title compound, C16H23N3O3, contains two morpholine rings, each of which adopts a chair conformation. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, leading to a S(6) ring. In the crystal, mol-ecules are linked into zigzag chains along the c-axis direction by C-H⋯O and C-H⋯π inter-actions.

A Novel Antimalarial Agent that Inhibits Protein Synthesis in Plasmodium falciparum
Angewandte Chemie International Edition, EarlyView.Compound 31 represents a promising avenue for the development as an antimalarial agent with a potent activity profile (PfNF54 IC50 ± s.d. = 3.9 ± 0.4 nM). It has a novel mode of action by binding to cytosolic ribosomal subunits, thereby inhibiting protein synthesis in the parasite.

Practical Catalytic Cleavage of C(sp3)−C(sp3) Bonds in Amines [PDF]
, 2019 The selective cleavage of thermodynamically stable C(sp3)−C(sp3) single bonds is rare compared to their ubiquitous formation. Herein, we describe a general methodology for such transformations using homogeneous copper-based catalysts in the presence of ...
