An Efficient Asymmetric Synthesis of 2-Substituted 1,4-Benzodiazepin-3-one as a Potential Molecular Scaffold

EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 8 2005
Nuria Cabedo
Abstract 2-Substituted 1,4-benzodiazepine-2-one compounds (9,12) were obtained by a highly diastereoselective alkylation of a seven-membered ring benzolactam (8) in the presence of (R)-phenylglycinol as a chiral inductor. The corresponding acid derivative (16) afforded a conformationally constrained structure suitable for preparing peptidomimetic analogues useful as a novel molecular scaffold. After cleavage of the chiral appendage this approach might also lead efficiently to enantiomerically pure 2-substituted benzodiazepines (15). (© Wiley-VCH Verlag GmbH & Co.

A novel asymmetric synthesis of tritium and carbon-14 labeled (R)-ibuprofen

JOURNAL OF LABELLED COMPOUNDS AND RADIOPHARMACEUTICALS, Issue 3 2006
Yinsheng Zhang
Abstract An efficient asymmetric synthesis of tritium and carbon-14 labeled R -ibuprofen was achieved in good overall yield (15% and 47%, respectively) and excellent enantiomerical excess (>98% e.e.), using (4R, 5S)-4-methyl-5-phenyl-2-oxazolidinone as a chiral auxiliary.
