The direct electrophilic cyanation of β-keto esters and amides with cyano benziodoxole.
The direct electrophilic α-cyanation of β-keto esters and amides has been developed using a hypervalent iodine benziodoxole-derived cyano reagent. The procedure is accomplished within 10 min and without the use of any catalyst in DMF, at room temperature. Thus, the highly functionalized quaternary carbon-centered nitriles were produced in high to excellent yields.
متن کاملCopper-catalyzed cascade reactions of α,β-unsaturated esters with keto esters
A copper-catalyzed cascade reaction of α,β-unsaturated esters with keto esters is reported. It features a copper-catalyzed reductive aldolization followed by a lactonization. This method provides a facile approach to prepare γ-carboxymethyl-γ-lactones and δ-carboxymethyl-δ-lactones under mild reaction conditions.
متن کاملOrganocatalytic asymmetric Michael-type reaction between β,γ-unsaturated α-keto ester and α-nitro ketone.
A Michael-type reaction of β,γ-unsaturated α-keto ester and α-nitro ketone was established. With a thiourea catalyst derived from cinchona alkaloid, the reactions afford products in 47-94% yields with 68-96% ee.
متن کاملPulse Radiolysis of Tetraphenylcyclobutane in Hexamethylphosphoric Triamide Solution
r-1, c-2, t-3, t-4-tetraphenvlcyclobutane (TPCB) was irradiated in dilute solutions of hexa methylphosphoric triamide (HMPT) with 20 ns pulses of 16 MeV electrons. Solvated electrons (e^iv) produced during the radiolysis of HMPT react with TPCB with k = (6 ± 1) • 109 1/mol s. Simultaneously with the decay of the optical absorption of the solvated electrons, the formation of the absorption of t...
متن کاملN-Heterocyclic Carbene Catalyzed Sulfenylation of α,β-Unsaturated Aldehydes.
An efficient N-heterocyclic carbene (NHC) catalyzed sulfenylation reaction of α,β-unsaturated aldehydes with N-(arylthio)phthalimide has been developed. A wide variety of α-thioenals can be obtained with good to excellent yields and excellent Z-configuration.
