Switchable palladium-catalyst reaction of bromomethyl sulfoxides, CO, and N-nucleophiles: Aminocarbonylation at Csp3 versus oxidative carbonylation of amines

The palladium-catalyzed reaction of alpha-bromomethyl sulfoxides, carbon monoxide, and N-nucleophiles follows different reaction pathways according to the catalytic system and the reaction conditions. The Pd-xantphos catalyst affords high yields of alpha-sulfinyl amides by an aminocarbonylation process and is the first example of this type of transformation for a nonbenzylic sp3-hybridized carbon. On the other hand, the oxidative carbonylation of amines occurs with alpha-bromomethyl sulfoxides, carbon monoxide, and catalytic Pd(PPh3)4 under aerobic conditions, yielding ureas and oxalamides from either primary or secondary amines. The reaction with ambident nucleophiles such as amino alcohols was highly selective and took place exclusively at the amino group despite the presence of the alcohol functionality. In parallel to the reaction paths for simple amines, amino alcohols were converted into hydroxy sulfinyl amides when the reaction was catalyzed by Pd-xantphos, while Pd(PPh3)4 catalyst afforded cyclic carbamates. The alkoxycarbonylation reaction of bromomethyl sulfoxides with simple alcohols and CO leading to the corresponding sulfinyl esters is also described.

Kinetics of N-bromination of 2-oxazolidinone

The kinetics of N-bromination of 2-oxazolidinone by transferor Br from sodium hypobromite, N-bromosuccinimide (NBS), or N-bromoacetamide (NBA) were determined spectrophotometrically, at pH between 4.6 and 12.45 (depending on the brominating agent). The reaction with hypobromite was of first order with respect to both the hypobromite and the substrate. The bromination of oxazolidinone with NBS (or NBA) has been found to be a reversible process of order one with respect to both NBA (or NBA) and oxazolidinone in the forward direction, and order one with respect to SI (or ACAM) and the resulting N-bromo-oxazolidinone in the other. The pH dependence of the reaction rate was in keeping with a mechanism in which all the brominating agents (HOBr, BrO -, NBS and NBA) react predominantly with the anion of the substrate. Bimolecular bromination rate constants increased in the order BrO- < NBA < NBS < HOBr. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C3H5NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 497-25-6, in my other articles.

Steric and electronic requirements of amide and ester groups in benzylidenemalonates

Stereoisomeric benzylidinemalonates have been synthesised. In the case of N-(2-ethoxycarbonyl-3-phenylpropenoyl)-2-oxazolidinone, both E- and Z-isomers could be obtained, but the Z-isomer isomerised (> 95%) to the E-isomer in the presence of catalytic amounts of Rh(I) complex catalysts. For ethyl tert-butylamidobenzalmalonate, the Z-isomer initially predominates under Knoevenagel conditions, but is very readily converted into the more stable E-isomer, which is here isolated stereoisomerically pure and is the only product of other synthetic routes. The configuration of benzylidinemalonates was established in two cases by X-ray crystallography, and the relative stability of the isomeric forms correctly simulated by MM2 calculations. In both the amide and oxazolidinone series, asymmetric hydrogenation catalysed by cationic Rh complexes gave a configurationally stable product cleanly but in low e.e..
