The title compound, C(8)H(16)N(2)O(4), is a Weinreb amide that is also an important inter-mediate for the preparation of ketones and aldehydes. The molecule possesses a centre of symmetry.

conclusions calcined coral/sodium nitrate as a new, efficient, and natural heterogeneous catalyst used in aldol condensation reaction of ketones and aldehydes led to β-hydroxyketones in good to high yields in appropriate condition. materials and methods marine coral (acropora sp.) was washed several times using methanol-ethyl acetate and deionized water and then dried in an oven at 80°c for 48 ...

We achieved highly enantioselective synthesis of cyclic 1,2-sulfamidates and -sulfamides via rhodium-catalyzed transfer hydrogenation, and also revealed one-pot preparation of cyclic N-sulfonylimines from α-hydroxy ketones.

A well-designed method for the preparation of a β-diketiminatolead(II) monofluoride has been developed using LPbNMe(2) (L = [CH{C(Me)(2,6-iPr(2)C(6)H(3)N)}(2)]) and pentafluoropyridine (C(5)F(5)N). The resulting LPbF was used for the synthesis of amidinatosilicon(II) monofluoride. Moreover the activation of a ketone was observed when the LPbF was treated with PhCOCF(3).

When exposed to hypoxia, intact mice, with elevated blood ketones, live longer than mice with normal blood ketones. To evaluate a possible mechanism responsible for this phenomenon a rat brain slice preparation was used to determine if brain tissue would utilize glucose or ketones preferentially during exposure to reduced oxygen. Reducing available oxygen in the incubation medium from 95%, in s...

ABSTRACT This study investigates the substrate profile of cycloalkanone monooxygenase and 2-oxo-Δ3-4,5,5-trimethylcyclopentenylacetyl-coenzyme A monooxygenase, two recently discovered enzymes of the Baeyer-Villiger monooxygenase family, used as whole-cell biocatalysts. Biooxidations of a diverse set of ketones were performed on analytical scale: desymmetrization of substituted prochiral cyclobu...
