Kinetic Study of the Pyridine-Catalyzed Selenolactonization of 4-Pentenoic Acid

Abstract: The kinetics and mechanism of the pyridine-catalyzed cyclofunctionalization of 4-pentenoic acid by means of PhSeX (X = Cl, Br) have been investigated spectrophotometrically, under pseudo-first order reaction conditions. The influence of the reac

Time-economical synthesis of selenofunctionalized heterocycles via I2O5-mediated selenylative heterocyclization

A time-economical and robust synthesis of various selenofunctionalized heterocycles was accomplished via I2O5-mediated selenocyclizations of olefins with diselenides. Using this method, 116 selenomethyl-substituted heterocycles were

Preparation of selenofunctionalized heterocycles via iodosobenzene-mediated intramolecular selenocyclizations of olefins with diselenides

An intramolecular selenocyclizations of olefins mediated by a commercially available hypervalent iodine(III) reagent, PhIO, was developed. This method provided access to a wide range of selenenylated heterocycles under ambient conditions. The striking advantages of this protocol over all previous methods include mild reaction conditions, easy operation, good yields, high levels of functional group compatibility, large–scale application and suitability for the late-stage functionalization of complex molecules of biological importance.

Synthesis, characterization and biological studies of organoselenium trans-palladium(II) complexes

Background: Over the years, transition metal complexes have exhibited significant antimicrobial and antitumor activity. It all started with cisplatin discovery, but due to the large number of side effects it shows, there is a growing need to find a new me

Electrochemical Difunctionalization of Olefines: Access to Selenomethyl-Substituted Cyclic Ethers or Lactones

A metal- and oxidant-free electrochemical method for preparing selenomethyl-substituted cyclic ethers or lactones via difunctionalization of olefines is presented. A series of selenomethyl-substituted cyclic ethers, particularly 9- and 11- membered, selen

Automated Electrochemical Selenenylations

Integrated electrochemical reactors in automated flow systems were utilised for selenenylation reactions. The automation allowed multiple electrochemical reactions of a programmed sequence to be performed in a fully autonomous way. Many functionalised selenenylated products were synthesised in short reaction times in good to high yields.

Preparation of Heterocycles via Visible-Light-Driven Aerobic Selenation of Olefins with Diselenides

The aerobic dehydrogenative cyclization of alkenes with easily accessible diselenides facilitated by visible light is reported. Notably, the features of this transition-metal-free protocol are pronounced efficiency and practicality, good functional group

A mild and efficient procedure for alkenols oxyselenocyclization by using ionic liquids

A mild and efficient procedure for the oxyselenocyclization of unsaturated alcohols by treatment with phenylselenyl chloride using ionic liquids as solvents/catalyzers has been developed. The reaction proceeds instantaneously under mild conditions with ab

Iodine-mediated acyloxyselenenylation of alkenes

In the presence of I2, an acyloxyselenenylation of alkenes with diselenides and carboxylic acids is developed. This metal-free iodine-mediated acyloxyselenenylation proceeds efficiently under mild reaction conditions, affording a series of 2-acyloxy-1-selenides with high regioselectivity and in moderate to good yields.

Ammonium Iodide Catalyzed Selenolactonization of Unsaturated Acids

A convenient procedure is developed for the preparation of selenolactones from unsaturated acids and diselenides using a catalytic amount of ammonium iodide in combination with m-chloroperoxybenzoic acid as the oxidant. This catalytic ring-closing method
