Green synthesis of new chiral 1-(arylamino)imidazo[2,1-]isoindole-2,5-diones from the corresponding α-amino acid arylhydrazides in aqueous medium.

New chiral 1-(arylamino)imidazo[2,1-]isoindole-2,5-dione derivatives were obtained in good to excellent yields via the cyclocondensation of 2-formylbenzoic acid and various α-amino acid arylhydrazides using water as the solvent in the presence of sodium dodecyl sulfate as the surfactant and under simple and minimum manipulation, without purification. The reaction is totally diastereoselective and gives access to the nitrogenated tricyclic core with a relative stereochemistry.

New palladium-oxazoline complexes: Synthesis and evaluation of the optical properties and the catalytic power during the oxidation of textile dyes.

The present paper describes the synthesis of new palladium-oxazoline complexes in one step with good to high yields (68-95%). The oxazolines were prepared from enantiomerically pure α-aminoalcohols. The structures of the synthesized palladium complexes were confirmed by NMR, FTIR, TOFMS, UV-visible spectroscopic analysis and X-ray diffraction.

Optimizing the ultrasound visualization of the endometrial-myometrial junction (EMJ).

Objectives: The aim of this study was to find the best 3D reconstruction technique to visualize the endometrial-myometrial junction (EMJ).

Methods: Retrospective observational study on 240 stored 3D volumes of 80 patients. The first author reconstructed the 2D midcoronal image without volume contrast imaging (VCI), with VCI set at 4 mm and with VCI set at 2 mm.

New chiral 4-substituted 2-cyanoethyl-oxazolines: synthesis and assessment of some biological activities.

This paper describes the synthesis of new enantiomerically pure 2-cyanoethyl-oxazolines in one step starting from a wide range of amino alcohols and 4-ethoxy-4-iminobutanenitrile with high to good yields (73-96%) via an appropriate procedure which can be used for a selective synthesis of mono-oxazolines. A simple operation as well as a practical separation is additional eco-friendly attributes of this method. All the synthesized compounds were identified and characterized with their physicochemical features and their spectral data ((1)H NMR, (13)C NMR and TOFMS ES(+)).

Determination of fetal body volume measurement at term with magnetic resonance imaging: effect of various factors.

Purpose: To evaluate various factors that potentially influence the fetal body volume (FBV) measurement using magnetic resonance imaging (MRI) and to analyze whether the technique of measurement could be simplified.

Materials And Methods: In 20 singleton pregnancies scheduled for a planned delivery, FBV measurements were performed by two independent operators on sagittal, axial and coronal planes and with various slice thickness and intersection gap, totalizing 100 examinations. MR estimation of fetal weight (MR-EFW) was calculated based on the equation developed by Baker.
