Addition of nitrile oxides to germyl-substituted ethylenes
The reactions of [2+3] cycloaddition of nitrile oxides to mono- and 1,2-disubstituted germylalkenes proceed regioselectively and resulted 5-Ge-substituted isoxazolines-2 from triethylvinyl- andExpand
Crystal structures and physicochemical properties of diltiazem base and its acetylsalicylate, nicotinate and L-malate salts
Diltiazem is a drug used as a calcium channel blocker in the treatment of cardiovascular disorders. Because of the poor aqueous solubility of the drug, its hydrochloride salt has been marketed. DueExpand
Fluoride ion catalyzed silylation of ketoximes by hydrosilanes
Silylation of aromatic and heteroaromatic oximes with hydrosilanes in the presence of system CsF/18-crown-6/benzene was studied. Silyl ethers were isolated in yields up to 78%. Mechanism of fluorideExpand
Synthesis, structure and cytotoxicity of 3-C, N, S, Se substituted benzo[b]selenophene derivatives.
Synthesis, molecular structure and cytotoxic activity of a series of 3-C, N, S, Se substituted benzo[b]selenophene derivatives on human fibrosarcoma HT-1080, mouse hepatoma MG-22A, and mouseExpand
Synthesis, structure and cytotoxicity of organoammonium selenites
New selenites of different organic bases have been prepared by the reaction of selenium dioxide with aliphatic and heterocyclic amines in an aqueous medium. Their structure was confirmed by 1 H, 13 CExpand
Hydrosilylation Of (Hetero)aromatic Aldimines in the Presence of a Pd(I) Complex
The reaction of triethylsilane with heterocyclic and aromatic azomethines, catalyzed by the [Pd(allyl)Cl]2 complex, was studied. It was found that the reaction is affected by the nature of theExpand
C-Quaternary Vinylglycinols by Metal-Catalyzed Cyclization of Allylic Bistrichloroacetimidates
Bistrichloroacetimidates (III) undergo highly regioselective cyclization in the presence of Pd or Lewis acid catalysts to give vinyloxazolines.
Synthesis of unsymmetric diynes by palladium and cesium fluoride catalyzed coupling of terminal bromoalkynes with alkynylstannane
The Stille reaction of unsymmetric diynes from terminal bromoalkynes with alkynylstannane in the presence of palladium catalyst and cesium fluoride was studied. The system (bromoalkyne:Expand
Betaines derived from amino and hydrazino acids as phase transfer catalysts
Abstract Betaines derived from α-, β- and γ-amino acids (obtained by alkylation of the corresponding amino acids with O-methyl-N.N'- diisopropylisourea) as well as β-hydrazino acids (prepared by de-Expand
