X-ray crystallography was used to confirm the structure of the enantio-enriched title compound, C10H12Cl2O, a bicylic enol ether. A bridged boat-like structure is adopted and the dichloromethylene C atom is positioned significantly removed from the c

Synthesis of a novel 1′,2′-oxetane-uridine bearing a 2′-C-methyl substituent, [1-(1′,3′-O-anhydro-3′-C-methyl-β- d -psicofuranosyl)uracil], is described. Key to its construction was the use of 6-O-(p-toluoyl)-1,2:3,4-di-O-isopropylidene-

2-Benzoyl-4,5-dihydrofuran (5) readily undergoes oxidation in air, during chromatography on silica, or following exposure to oxidising agents (MCPBA, DMDO), to give 2-benzoylbutyrolactone (6) and tricycle 7 as the major products. © 2006 Elsevier Ltd

2,2-Disubstituted pyrrolidin-3-ones are prepared in three steps from simple dihydropyran derivatives; the key spiro-N,O-acetal intermediate is a useful N-sulfonylketoiminium ion precursor. This route represents a formal synthesis of the indolizidine

Biological Shape Analysis.
The identification of skeletons cannot always be achieved using DNA and/or dental records. This is especially true of remains thought to belong to US military personnel that were recovered from the Korean War. A solution to this problem may be found
