Enantioselective fluoroamination: 1,4-addition to conjugated dienes using anionic phase-transfer catalysis.
Chiral-anion phase-transfer catalysis (PTC) has been applied towards the enantioselective fluorocyclization reactions of 1,3-dienes. The method affords unprecedented fluorinated benz[f]isoquinoline and octahydroisoquinoline products in high yields and up to 96 % ee. New fluorinated amine reagents outperformed Selectfluor in the desired transformation.
متن کاملPhase-transfer catalysis for synthesis of ethyl 2-(4-nitrophenoxy)acetate under sonication- kinetic aspects
Ultrasound assisted phase-transfer catalyzed preparation of ethyl 2-(4-nitrophenoxy)acetate from the corresponding p-nitrophenol and ethyl 2-bromoacetate using the mild solid base, anhydrous potassium carbonate, under very mild conditions is reported. The solid-liquid reactions were performed in a batch reactor equipped with reflux condenser, and ultrasonic irradiations were introduced using an...
متن کاملSynthesis of 1-(isopentyloxy)-4-nitrobenzene under ultrasound assisted liquid-liquid phase-transfer catalysis
In this paper, we report the reaction of isoamyl alcohol and 1-chloro-4-nitrobenzene was carried out in a batch reactor under aqueous-organic biphasic conditions using the techniques like phase transfer catalysis and ultrasound irradiation. Tetrabutylammonium bromide (TBAB) was employed as the phase transfer catalyst. The reaction is greatly enhanced by adding a small quantity of phase-transfer...
متن کاملAsymmetric electrophilic fluorination using an anionic chiral phase-transfer catalyst.
The discovery of distinct modes of asymmetric catalysis has the potential to rapidly advance chemists' ability to build enantioenriched molecules. As an example, the use of chiral cation salts as phase-transfer catalysts for anionic reagents has enabled a vast set of enantioselective transformations. Here, we present evidence that a largely overlooked analogous mechanism wherein a chiral anioni...
متن کاملInterfacial Mechanism and Kinetics of Phase-Transfer Catalysis
As the chemical reactants reside in immiscible phases, phase transfer (PT) catalysts have the ability to carry one of the reactants as a highly active species for penetrating the interface, into the other phase where the reaction takes place, and to give a high conversion and selectivity for the desired product under mild reaction conditions. This type of reaction was termed ‘‘phase-transfer ca...
