Background context Spinal cord compression and fracture are possible complications of spine metastasis and multiple myeloma. Prompt diagnosis and treatment of threatening lesions are likely to reduce the frequency of these dreaded complications. Purp

Recurrences or second primary head and neck cancers meant, for a long time, therapeutic dead ends. Surgery was the standard treatment, but could only be achieved in 25% of the patients. The GETTEC-GORTEC (99-01) randomized trial showed that radiochem

β‐Hydroxy nitroethanol ethers are prepared by selective alcoholysis of oxiranes. The best results are obtained using a clay (monmorillonite K10) or a π‐acid (TCNE) as the catalyst.

Chiral secondary vic-diamines of diaminobutanediols have been efficiently prepared from L-tartaric acid. Their selective cyclization led to cis-tetraheterodecalines having a (1S,6S)-2,7-diaza-4,9-dioxa[4.4.0]decane core system.

1-Bromo-3-buten-2-one is investigated as a building block for organic synthesis. Reduction to the corresponding alcohol works best with lithium aluminium hydride, reaction with primary amines gives 5-membered-aza-heterocycles in moderate yields and r

Pure mixed triglycerides can be prepared from diglycerides and by acylolysis of glycerolformal tosylate without isomerization. The last fatty chain, with or without a functional group, can be introduced on any position of glycerol.

The enantiomeric purity of a chiral compound is determined by NMR spectroscopic analysis of the diastereomers formed with a chiral derivatizing agent. Fluorinated O-aryllactic acids (FAC) 1 are efficient chiral reporters, whose spectacular remote ani
