High-Throughput Screening of the Asymmetric Decarboxylative Alkylation Reaction of Enolate-Stabilized Enol Carbonates Asymmetric Decarboxylative Alkylation Reaction of Enolate-Stabilized Enol Carbonates
SYNLETT 2010, No. 11, pp 1712–1716xx.xx.2010 Advanced online publication: 14.06.2010 DOI: 10.1055/s-0030-1258094; Art ID: Y00510ST © Georg Thieme Verlag Stuttgart · New York Abstract: The use of high-throughput screening allowed for the optimization of reaction conditions for the palladium-catalyzed asymmetric decarboxylative alkylation reaction of enolate-stabilized enol carbonates. Changing t...
متن کاملCopper-Stabilized Sulfur-Microporous Carbon Cathodes for Li–S Batteries
wileyonlinelibrary.com interact with two Li atoms per S atom, the S cathode can provide reversible high capacity of 1675 mAh g -1 at average potentials of 2.0 V, [ 1–3 ] which is 10× higher energy density than that of classical commercial LiCoO 2 cathode. Since the capacity of current LiCoO 2 -graphite Li-ion battery is controlled by LiCoO 2 cathode, replacement of expensive LiCoO 2 with cheap ...
متن کاملHigh-Throughput Screening of the Asymmetric Decarboxylative Alkylation Reaction of Enolate-Stabilized Enol Carbonates.
The use of high-throughput screening allowed for the optimization of reaction conditions for the palladium-catalyzed asymmetric decarboxylative alkylation reaction of enolate-stabilized enol carbonates. Changing to a non-polar reaction solvent and to an electron-deficient PHOX derivative as ligand from our standard reaction conditions improved the enantioselectivity for the alkylation of a keta...
متن کاملApplication of furyl-stabilized sulfur ylides to a concise synthesis of 8a-epi-swainsonine.
The total synthesis of 8a-epi-swainsonine has been achieved in 20% overall yield from R-glyceraldehyde dimethylacetonide 3 through epoxidation with the achiral furyl-substituted sulfonium ylide 2d as one of the key steps.
متن کاملThe a-Cyano-a-phenylacetic Acid Keto-Enol System. Flash Photolytic Generation of the Enol in Aqueous Solution and Determination of the Keto-Enol Equilibrium Constants and Acid Dissociation Constants Interrelating All Keto and Enol Forms in That Medium
The enol of a-cyano-a-phenylacetic acid was observed as a short-lived transient species formed upon flash photolytic generation of phenylcyanoketene by a photo-Wolff reaction of a-cyano-a-diazoacetophenone followed by hydration of the ketene. Rates of ketonization of the enol were measured in dilute hydrochloric acid solutions and acetic acid, biphosphate ion, tris(hydroxymethyl)methylamine, an...
