Multi‐site Cooperativity in Alkali‐Metal‐Exchanged Faujasites for the Production of Biomass‐Derived Aromatics
The catalytic Diels-Alder cycloaddition-dehydration (DACD) reaction of furanics with ethylene is a promising route to bio-derived aromatics. The reaction can be catalyzed by alkali-metal-exchanged faujasites. Herein, the results of periodic DFT calculations based on accurate structural models of alkali-metal-exchanged zeolites are presented, revealing the fundamental roles that confinement and ...
متن کاملReaction of dialkyl carbonates with alcohols: Defining a scale of the best leaving and entering groups*
A series of dialkyl and methyl alkyl carbonates has been synthesized and their reactivity investigated. The behavior of preferential leaving and entering groups for the newly synthesized carbonates has been accurately investigated. Both experimental and computational studies agreed that the scale of leaving groups follows the trend: PhCH2O –, MeO– ≥ EtO–, CH3(CH2)2O –, CH3(CH2)7O – > (CH3)2CHO ...
متن کاملAlkylation of 2,4-(1H,3H)-quinazolinediones with dialkyl carbonates under microwave irradiations.
Alkylation is a very important chemical reaction which modifies the biological properties of drugs. Quinazolinedione derivatives are of considerable interest due to their wide array of pharmacological properties.We now report application of a practical alkylation procedure to several quinazolinediones, including pelanserine (5f), which shows antihypertensive properties, 1-methyl-3-(2'-phenyleth...
متن کاملSynthesis, Characterization and Fungicidal Activity of Some Dialkyl Alkylphosphonates and Dialkyl Phenylphosphonates
Some dialkyl alkylphosphonates and dialkyl phenylphosphonates were synthesized by the reactions between trialkyl phosphite and alkyl/aryl halide in the presence of benzene. The synthesized compounds were characterized by elemental analysis, thin layer chromatography (TLC), fourier –transform infrared, ( 1 H, 13 C) nuclear magnetic resonance (NMR) spectroscopic techniques. In vitro fungicidal ac...
متن کاملEnantioselective synthesis of hindered cyclic dialkyl ethers via catalytic oxa-Michael/Michael desymmetrization.
An asymmetric oxa-Michael/Michael cascade reaction of p-quinols and α,β-unsaturated aldehydes provides access to hindered dialkyl ethers. A highly enantioselective oxa-Michael addition of a tertiary alcohol precedes an intramolecular cyclohexadienone desymmetrization, which allows for the concomitant formation of four contiguous stereocenters in a single step. The highly functionalized bicyclic...
