Photoluminescent well-organised films

24-Sep-2008

Takayoshi Sasaki and colleagues at the National Institute of Materials Science, Tsukuba, and co-workers from the University of Tsukuba, Japan have prepared rare earth hydroxide films by trapping micrometer-sized crystals at a hexane-water interface and then transferring them to a substrate. The ...

Marine natural product synthesis

23-Sep-2008

Ian Paterson and Natalie Miller from Cambridge University have developed an 18 step synthesis, which incorporates a Jacobsen hetero Diels-Alder reaction as the key step. This produces the marine product in an overall 5.8% yield. Neopeltolide is a structurally complex marine natural product that ...

New synthetic route to oxindoles

12-Aug-2008

Peter Kündig and colleagues from Geneva University, Switzerland and Stephen Marsden and co-workers at the University of Leeds, in the UK, have developed an asymmetric Pd/N-heterocyclic carbene (NHC) - catalysed intramolecular -arylation of amide enolates, containing heteroatom sustituents. This ...
