Acid-catalyzed reactions of aromatic aldehydes with ethyl diazoacetate: an investigation on the synthesis of 3-hydroxy-2-arylacrylic acid ethyl esters.
Several commercial Lewis acids, including those of the Bronsted type, specifically HBF(4).OEt(2), are able to catalyze the reaction between aromatic aldehydes and ethyl diazoacetate to produce 3-hydroxy-2-arylacrylic acid ethyl esters and 3-oxo-3-arylpropanoic acid ethyl esters. Reactions catalyzed by the iron Lewis acid [(eta(5)-C(5)H(5))Fe(+)(CO)(2)(THF)]BF(4)(-) (i.e., 1) have the best yield...
متن کاملDielectric and Thermodynamic Properties of 2, 3-Butanediol + 2-ethyl-1-hexanol Mixtures
Experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-BD, in2-ethyl-1-hexanol, 2EH, were reported for various mole fractions and temperatures (298.2-308.2) Kand they were used to calculate dielectric parameters such as Kirkwood correlation factor, excesspermittivity and Bruggeman parameter. These parameters were used to carry out temperaturedependent die...
متن کاملSynthesis and Evaluation of Anti-acetylcholinesterase Activity of 2-(2-(4-(2-Oxo-2-phenylethyl)piperazin-1-yl) ethyl)Isoindoline-1,3-dione Derivatives with Potential Anti-Alzheimer Effects
Objective(s): Alzheimer's disease (AD) is a neurodegenerative disorder in elderly patients. Decrease in cholinergic neurotransmission is the main known cause in the pathophysiology of the disease. Improvement and potentiation of the cholinergic system could be beneficial for treatment of the AD. Acetylcholinesterase inhibitors such as donepezil can enhance the duration of action of a...
متن کاملPURINE ALKYLATING AGENTS 2 , 6-DIAMINO-8-HALO ALKYL PURINES (POTENTIAL ANTI - MALARIALS)
Haloalkyl purines i.e. 2,6-diamino-8-(chloromethyl) purine 10; 2, 6-diamino-X- (chloromethyl) purine 17; 2,6-diamino-8-(chloropropylp) urine 18; were synthesized by two distinct but facile methods. The N-alkylating potential of 2, 6-diamino-8- (chloromethyl) purine was investigated. The following products 2,6-diamino-8-(Nbenzyl- N-methyl) purine 11; 2,6-diamino-8-(4-nitro anilinomethyl) pur...
متن کاملProphage induction by alkylating ethyl methylaminosulfonate.
Treatment of the lysogenic strain M. lysodeikticus 53-40 (N5) with ethyl methylaminosulfonate results in a slight increase in infective center concentration of N5 phages which is only detectable once disturbing cells had been eliminated by lysozyme. After conversion of ethyl methylaminosulfonate with radioactive labelled guanosine at 37 degrees C, N7-ethyl-guanine could be ascertained. Therefor...
