Microwave-promoted iminyl radical cyclizations can be terminated by trapping with TEMPO, affording functionalized adducts. The use of alkynes as radical acceptors delivers a range of 2-acylpyrroles in good yields. Toxic and hazardous reagents, which are frequently employed in radical reactions, are not required. The O-phenyl oxime ether substrates are constructed in a single step from readily available ketones.

Abstract: 1-Bromovinyl and vinyl methyl sulfones undergo 1,3-dipolar cycloaddition reactions with azomethinylides generated in situ from ethyl N-benzylideneglycinates under the action of silver acetate and triethylamine (toluene, 20°C, 48 h) to form ethyl
Electrolytic Investigations of 2-Azido-2,4-pentadien-1-ones

Cathodic reduction of 2-azido-2,4-pentadien-1-ones under slightly protic conditions result in aminodienones, whereas under acetylating conditions only the methyl-N,N-diacetylaminodienoates could be prepared in resonable yields.The low reduction potential
