Decarboxylative radical addition to vinylsulphones and vinylphosphonium bromide: Some further novel transformations of geminal (pyridine-2-thiyl) phenylsulphones

Irradiation of O-acyl derivatives 1 of N-hydroxy-2-thiopyridone with visible light in the presence of phenyl vinyl sulphone or vinyl triphenylphosphonium bromide leads to the corresponding adducts 8 and 9 which can undergo a wide variety of further transformations.

THE INVENTION OF RADICAL CHAIN REACTIONS. PART XIV. A DECARBOXILATIVE RADICAL ADDITION TO QUINONES

Irradiation of esters 3 derived from aliphatic or alicyclic carboxylic acids and N-hydroxy-2-thiopyridone in the presence of various quinones gives high yields of the corresponding adducts (e.g. 9) with net loss of carbon dioxide.

CONCISE SYNTHESES OF L-SELENOMETHIONINE AND OF L-SELENOCYSTINE USING RADICAL CHAIN REACTIONS

L-Selenomethionine and L-selenocystine were prepared in high overall yields from protected L-glutamic and L-aspartic acid derivatives respectively.Irradiation of the mixed anhydrides (esters) derived from 4 (e.g. 15) in the presence of dimethyldiselenide provided the protected L-selenomethionine 16 directly.We have shown that triselenocyanide Se3(CN)2 can serve as an efficient selenocyanating agent for radicals; the selenocyanide group is a good precursor for the diselenide moiety of L-selenocystine.
