Synthesis of isoxazolines and isoxazoles using poly(ethylene glycol) as support

A general method for the liquid-phase syntheses of isoxazoles and isoxazolines through a 1,3-dipolar cycloaddition is described. The poly(ethylene glycol) (PEG)-supported alkyne 2 or alkene 6 reacted with nitrile oxides generated in situ from aldoximes 3, followed by cleavage from the PEG, to give isoxazoles or isoxazolines in good yield and purity.

Visible Light-Promoted Recyclable Carbon Nitride-Catalyzed Dioxygenation of β,γ-Unsaturated Oximes

A visible-light-induced dioxygenation of β,γ-unsaturated oximes for the synthesis of diverse useful isoxazolines bearing a hydroxyl moiety was developed by employing graphitic carbon nitride (g-C3N4) as a heterogeneous photocatalyst under an air atmosphere. Noted that, the eminent advantages of this metal-free protocol include step economy, easy operation, a recyclable photocatalyst, external reductant-/oxidant-free and mild reaction conditions. Additionally, mechanistic studies indicated hydroxyl radical was generated under the photocatalysis of g-C3N4.

Organophotocatalytic Generation of N- and O-Centred Radicals Enables Aerobic Oxyamination and Dioxygenation of Alkenes

A cooperative TEMPO and photoredox catalytic strategy was applied for the first time to the direct conversion of N?H and O?H bonds into N- and O-centred radicals, enabling a general and selective oxidative radical oxyamination and dioxygenation of various

Synthesis of hydroximoyl chlorides from aldoximes and benzyltrimethylammonium tetrachloroiodate (BTMA ICl4)

Benzyltrimethylammonium tetrachloroiodate (BTMA ICl4) acts as a convenient reagent to convert aldoximes to hydroximoyl chlorides by a simple procedure. When an aldoxime is treated with BTMA ICl4 in dichloromethane, the suspension of BTMA ICl4 shortly disappears as the reaction proceeds. The resulting BTMA ICl2 can be precipitated out by adding diethyl ether. Not only stable aromatic and heteroaromatic hydroximoyl chlorides can be isolated by this method but also rather unstable aliphatic hydroximoyl chlorides can be generated in situ. 1,3-Dipole trapping with a dipolarophile is performed in one flask and in some cases the chlorination is successfully performed in the presence of dipolarophile and triethylamine. Effect of MS 4A has been examined. (C) 2000 Elsevier Science Ltd.
