Synthesis of (−)-epibatidine [PDF]
An asymmetric synthesis to the dendrobatid alkaloid (−)-epibatidine has been described, featuring chiral resolution of both optically pure 7-azabicyclo[2.2.1]heptanecarboxylic acid, and subsequent transformations to (−)-epibatidine.

Synthesis of 5-Aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones
A two-stage synthesis of 5-aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones (56–66% overall yields) was carried out by refluxing 5-aroyl-3-(benzyloxy)-2-(het)aryl-4H-pyran-4-ones with ammonium acetate in AcOH and subsequent debenzylation.

Rapid changes in Atlantic grey seal milk from birth to weaning – immune factors and indicators of metabolic strain [PDF]
True seals have the shortest lactation periods of any group of placental mammal. Most are capital breeders that undergo short, intense lactations, during which they fast while transferring substantial proportions of their body reserves to their pups ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Metabolomics application in maternal-fetal medicine [PDF]
Metabolomics in maternal-fetal medicine is still an "embryonic" science. However, there is already an increasing interest in metabolome of normal and complicated pregnancies, and neonatal outcomes. Tissues used for metabolomics interrogations of pregnant
