چکیده
In the title compound, C24H23N5O3, the oxindole ring system is nearly planar, with a dihedral angle between the two fused rings of 3.3 (1)°. In the fused pyrrolo-oxazole ring system, the oxazole and pyrrolidine rings adopt envelope conformations with the spiro C atom and one of the methyl-ene C atoms, respectively, as the flap atoms. In the crystal, mol-ecules are linked into a helical chain along the b axis via C-H⋯O inter-actions generating R 2 (1)(7) and R 2 (2)(8) ring motifs.

X-ray analysis and structural characterization of 2-phenyl-6-aza-1,3- dioxa-2-borabenzocyclononenones
Nine new monomeric boronates of the type 2-phenyl-6-aza-1,3-dioxa-2-borabenzocyclononen-4-ones (3a /3i) were prepared from N -(2-hydroxybenzyl)-a-aminoacids 1a /1i and phenylboronic acid 2 using 20:1 benzene /DMSO mixtures. The compounds were characterized by H-, C-, B-, Nand 2D-NMR (HETCOR, NOESY and COLOC) experiments, FT infrared, mass spectra and elemental analysis. Suitable monocrystals of...
متن کاملAzirinium ylides from α-diazoketones and 2H-azirines on the route to 2H-1,4-oxazines: three-membered ring opening vs 1,5-cyclization
Strained azirinium ylides derived from 2H-azirines and α-diazoketones under Rh(II)-catalysis can undergo either irreversible ring opening across the N-C2 bond to 2-azabuta-1,3-dienes that further cyclize to 2H-1,4-oxazines or reversibly undergo a 1,5-cyclization to dihydroazireno[2,1-b]oxazoles. Dihydroazireno[2,1-b]oxazoles derived from 3-aryl-2H-azirines and 3-diazoacetylacetone or ethyl diaz...
متن کاملStereoselective synthesis of (all-Z)-hentriaconta-3,6,9,12,15,19,22,25,28-nonaene.
Several microorganisms produce small quantities of polyunsaturated hydrocarbons and such natural products are of interest. Starting from the ethyl ester of eicosapentaenoic acid, the total synthesis of the natural product (all-Z)-hentriaconta-3,6,9,12,15,19,22,25,28-nonaene has been achieved in eight steps and 15% overall yield. The synthesis is based on a stereoselective Wittig reaction and co...
متن کامل9,10-Dioxa-1,2-diaza-anthracene derivatives from tetrafluoropyridazine
Reaction of tetrafluoropyridazine with catechol gives a tricyclic 9,10-dioxa-1,2-diaza-anthracene system by a sequential nucleophilic aromatic substitution ring annelation process, further extending the use of perfluoroheteroaromatic derivatives for the synthesis of unusual polyfunctional heterocyclic architectures. The tricyclic scaffold reacts with amines and sodium ethoxide providing a short...
متن کاملElectrochemical behavior of ascorbic acid at a 2,2'-[3,6-Dioxa-1,8-octanediylbis(nitriloethylidyne)]-bis-hydroquinone carbon paste electrode.
Electrocatalytic oxidation of ascorbic acid (AA) at a carbon paste electrode, chemically modified 2,2'-[3,6-dioxa-1,8-octanediylbis(nitriloethylidyne)]-bis-hydroquinone, was thoroughly investigated. The results of cyclic voltammetry, double potential-step chronoamperometry, linear sweep voltammetry and differential pulse voltammetry (DPV) studies were used for the prediction of the mechanism of...
