Mild and efficient cyanuric chloride catalyzed Pictet–Spengler reaction
A practical, mild and efficient protocol for the Pictet-Spengler reaction catalyzed by cyanuric chloride (trichloro-1,3,5-triazine, TCT) is described. The 6-endo cyclization of tryptophan/tryptamine and modified Pictet-Spengler substrates with both electron-withdrawing and electron-donating aldehydes was carried out by using a catalytic amount of TCT (10 mol %) in DMSO under a nitrogen atmosphe...
متن کاملReaction of Ampicillin and Amoxicillin with Alcohols
HPLC/ESI-MS analyses of alcohol solutions of ampicillin and amoxicillin have shown that the two drugs react very readily with alcohols (methanol and ethanol) at room temperatures, without the presence of any catalyst. Products of methanolysis were detected even when methanol was used as a mobile phase, in HPLC/ESI-MS analysis of a water solution of ampicillin and amoxicillin. Therefore, neither...
متن کاملConvenient syntheses of cyanuric chloride-derived NHC ligands, their Ag(I) and Au(I) complexes and antimicrobial activity.
Convenient syntheses of mono- and bis-imidazolium 1,3,5-triazine derivatives bearing piperidine and morpholine substituents are reported. In situ deprotonation of the mono-imidazolium salts and reaction with Ag2O or Au(tht)Cl (tht = tetrahydrothiophene) precursors affords the corresponding Ag(NHC)Cl and Au(NHC)Cl carbene complexes. In the presence of Ag(I) or Au(I) salts the bis-imidazolium pin...
متن کاملKINETIC STUDY OF THE REACTION OF 2,2’-BIPYRIDYL CHROMIUM PEROXIDE WITH ALCOHOLS
The rate constants and activation parameters are reported for the oxidation of methanol, ethanol, propanol, and isopropanol by 2,2’-bipyridyl chromium peroxide (BPCP) over the temperature range of 35° to 50°C.
متن کاملAn efficient and convenient synthesis of quinazoline derivatives catalyzed by cyanuric chloride in water
In this work, an eco-friendly procedure for the preparation of 2,3-dihydroquinazoline-4(1H)-ones was developed by condensation reaction of benzylic and heterocyclic aldehydes with 2-aminobenzamide in the presence of catalytic amounts of cyanuric chloride (2,4,6-trichloro-1,3,5-triazin) as an available and inexpensive organo-catalyst under aqueous media as a green conditions. The new co...
