1H and 13C NMR study of 2-hydroxyglutaric acid and its lactone

Determination of the level and absolute configuration of 2-hydroxyglutaric acid in a patient’s urine is a method of diagnosing two metabolic diseases. Such a determination can be done with the aid of NMR spectroscopic methods. In this paper the careful interpretation of 1H and 13C NMR spectra of this metabolite and its lactone measured under conditions used in biomedical assays is reported. The 1H chemical shifts and spin-spin coupling constants were derived using the total lineshape analysis method. Copyright

Cutting-Edge and Time-Honored Strategies for Stereoselective Construction of C-N Bonds in Total Synthesis

The main objective of this review is to provide a comprehensive survey of methods used for stereoselective construction of carbon-nitrogen bonds during the total synthesis of nitrogen-containing natural products that have appeared in the literature since 2000. The material is organized by specific reaction in order of decreasing number of applications in natural product synthesis. About 800 total syntheses of natural products with stereogenic carbon-nitrogen bonds described since 2000 have been reviewed.

A facile one pot C[sbnd]C and C[sbnd]N bond formation for the synthesis of spiro-benzodiazepines and their cytotoxicity

An efficient, multicomponent and environmentally benign protocol has been developed for the synthesis of spiro-benzodiazepines through C[sbnd]C and C[sbnd]N bond formations in a single step. This one-pot protocol proceeds via three component reaction of o-phenylenediamines, tetronic acid and isatins by using mild and inexpensive catalyst like sulphamic acid in water. A variety of spiro-benzodiazepine derivatives has been synthesized in excellent yields by using this protocol in a shorter reaction time. All the synthesized compounds were evaluated for their cytotoxic potential on different human cancer cell lines and most of the compounds exhibited moderate to good cytotoxic activity, while some of them like 4f, 4h, 4i, 4j and 4q showed promising cytotoxicity with IC50 values ranging between 1.14 and 1.69 muM.

Inversion of enantioselectivity in the hydrogenation of ketopantolactone on platinum modified by ether derivatives of cinchonidine

Asymmetric hydrogenation of ketopantolactone was studied on a 5 wt% Pt/Al2O3 catalyst in the presence of cinchonidine and its O-methyl, -ethyl, -phenyl and -trimethylsilyl derivatives. Inversion of enantioselectivity with the latter two bulky substituents proved that in the enantiodifferentiating step cinchonidine adsorbs via the quinoline ring lying approximately parallel to the Pt surface. The striking nonlinear effect observed with cinchonidine-O-phenyl-cinchonidine mixtures is attributed to differences in the adsorption strength and geometry of the modifiers.
