Novel types of compounds, N-tributylstannyl-2-oxazolidinone (4a) and tetrahydro-2H-1,3-oxazin-2-one (4b), are formed from the adduct of (n-Bu3Sn)2O (1) with omega-haloalkyl isocyanate (2), and the subsequent coupling reaction with alkyl halides gives a variety of N-substituted 2-oxazolidinones and tetrahydro-2-oxazinones in a one-pot procedure.Both the cyclization and the coupling reaction proceed quantitatively in the presence of HMPA which enhances the reactivity of the Sn-heteroatom bond by coordination.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 497-25-6. Electric Literature of 497-25-6

(Figure presented) The kinetics of the reactions of amide and imide anions 2a-o with benzhydrylium ions 1a-i and structurally related quinone methides 1j-q have been studied by UV-vis spectroscopy in DMSO and acetonitrile solution. The second-order rate constants (log k2) correlated linearly with the electrophilicity parameters E of 1a-q according to the correlation log k 2 = s(N + E) (Angew. Chem., Int. Ed. Engl. 1994, 33, 938-957), allowing us to determine the nucleophilicity parameters N and the nucleophile-specific parameters s for these nucleophiles. The reactivities of all sulfonamide and diacylimide anions are found in a relatively small range (15 < N < 22). Comparison with structurally related carbanions revealed that amide and imide anions are less reactive than carbanions of the same pK aH. These effects can be attributed to the absence of resonance stabilization of one of the lone pairs in the amide or imide anions. As amide and imide anions are exclusively attacked at nitrogen by benzhydrylium ions, Kornblums interpretation of the ambident reactivity of amide anions has to be revised.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Computed Properties of C10H11NO2. Introducing a new discovery about 102029-44-7, Name is (R)-4-Benzyl-2-oxazolidinone

A synthesis of a precursor 2 for the Elisabethin A skeleton is reported. Containing a masked quinone and a (E,Z)-diene sub-unit, it has the required elements for the envisaged intramolecular Diels-Alder reaction to form the tricyclic system of Elisabethin A. Starting from methylresorcinol, the sequence involves the preparation of an arylacetic acid, which was alpha-alkylated by a chiral building block. Subsequent HWE reaction and cis-selective Wittig olefination furnished the diene with the desired geometry.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 102029-44-7 is helpful to your research. Computed Properties of C10H11NO2

Formula: C10H11NO2, Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments.

Novel aspartate and succinate CGRP full antagonists were identified through core modification of a potent lead CGRP antagonist, BMS-694153. While aspartates were much less active and had a flat SAR, some of the succinates were very potent CGRP full antagonists and matched the potency of BMS-694153. The most potency resides in the S enantiomer as demonstrated through an asymmetric synthesis.

Structure-selectivity comparisons are made between chiral dirhodium(II) tetrakis(methyl 2-oxopyrrolidine5-carboxylates), Rh2(5S-MEPY)4 and Rh2(5R-MEPY)4 (5), and dirhodium(II) tetrakis(4-benzyl-2- oxazolidinones), Rh2(4R-BNOX)4 and Rh2(4S-BNOX)4 (6), to ascertain and understand their relative effectiveness as catalysts for enantiocontrol in metal-carbene transformations. The syntheses, spectral characteristics, and X-ray structures for these dirhodium(II) compounds are reported. Each possesses two oxygen- and two nitrogen-donor atoms bound to each . octahedral rhodium with a cis orientation of the nitrogen ligands. The Rh2(MEPY)4 catalysts are significantly more effective than those of Rh2(BNOX)4 in providing a high level of enantiocontrol in intermolecular and intramolecular cyclopropanation reactions, in intermolecular cyclopropenation reactions, and in intramolecular C-H insertion reactions of diazoacetates and diazoacetamides, often reaching >90% enantiomeric excesses. Molecular mechanics calculations that were able to reproduce the X-ray structures of Rh2(5S-MEPY)4 and Rh2(4R-BNOX)4 have been employed to obtain the preferred conformation of the intermediate metal-carbene, but the absolute configurations of cyclopropanation products are opposite to those predicted from the preferred metal-carbene conformation. However, conformational energy minima of the styrene-carbene complex predict the observed enantiomer preference.
