A convenient synthesis of gimeracil

A practical three-step synthetic approach to gimeracil in a 68% overall yield is described, using 2,4-dimethoxypyridine as the starting material with 3,5-dichloro-2,4-dimethoxypyridine and 3,5-dichloro-2,4-dihydroxypyridine as intermediates. The advantages of this procedure include short reaction steps, simple operation and good yield.

Effect of variation in nestling hunger levels on the begging behaviour of nestlings and the provisioning behaviour of adult American Kestrels

Little is known about how variation in nestling begging intensity influences the behaviour of adult raptors and how responses of adult males and females to such variation might differ. Our objective was to manipulate the begging intensity of nestling American Kestrels (Falco sparverius) and examine the responses of adults.

Nuclease activity of diaza-crown ether complexes of cerium(III) with different functional groups as side arms

Cerium(III) complexes of two ligands of a diaza-crown ether with different functional groups as side arms were synthesised and characterised. The catalytic ability of the cerium(III) complexes for pUC19 DNA cleavage was investigated and compared using agarose gel electrophoresis.

Now available on Fast Track: Oganesson: a most unusual ‘inert gas’

Oganesson, with the symbol Og, is the artificially prepared (i.e. ‘man-made’) elementwith atomic number 118, previously known as eka-radon or Uuo (‘ununoctium’), and recently ‘blessed’ with an official name by IUPAC3. Atoms of the element were first produced using the U400 cyclotron at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, via a heavy-ion fusion reaction utilising collision of a <sup><...
