We describe the catalytic amination of beta-(hetero)arylethyl ethers with amines using the organic superbase t-Bu-P4 to obtain beta-(hetero)arylethylamines. The reaction has a broad substrate scope and allows the transformations of electron-deficient and electron-neutral beta-(hetero)arylethyl ethers with various amines including pyrrole, N-alkylaniline, diphenylamine, aniline, indole, and indoline derivatives. Mechanistic studies indicate a two-reaction pathway of MeOH elimination from the substrate to form a (hetero)arylalkene followed by the hydroamination of the alkene.

Couplin of organotin reagents Bu3SnAr (Ar = 2- or 3-thienyl, 2- or 3-pyridyl) with ClCOCH2CH2CO2Et in the presence of PdCl(CH2Ph)(PPh3)2 yields beta-ketoesters ArCOCH2CH2CO2Et which were converted with hydrazine hydrate into 6-substituted 4,5-dihydropyridazin-3(2H)-ones, and thence to 3-halogeno-6-substituted pyridazines.The latter also couple under similar conditions with Bu3SnAr to yield 3-heteroarylpyridazines.With catalysts, coupling of ClCOCO2Et and Bu3SnAr proceeds with loss of carbon monoxide giving ArCO2Et, but without catalyst ArCOCO2Et is formed from which the3-heteroarylquinoxalin-3-one is prepared.The reactions of Bu3SnAr with 4-XC6H4Br (X = H,-OMe, -CN, -NO2) are also described.

A convenient and versatile synthetic approach to substituted 1,3-oxazolo[4,5-d]pyridazinones is developed. The oxazole ring was formed upon reaction of 5-amino-4-hydroxy-3(2H)-pyridazinone with various carboxylic acid derivatives using a microwave-assisted procedure, which favors the reaction time and purity of the resulting products. The developed methodology is suitable for rapid, parallel, automated synthesis of oxazolopyridazinone libraries.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 4,5-Dichloro-3(2H)-pyridazinone, you can also check out more blogs about932-22-9
