Study on Radical Amidation onto Aromatic Rings with (Diacyloxyiodo)arenes
摘要:
Sulfonamides of primary amines bearing an aromatic ring at the gamma-position were treated with (diacyloxyiodo)arenes and:iodine under irradiation conditions with;a tungsten-lamp to give the corresponding 1,2,3,4-tetrahydroquinoline derivatives in moderate to good yields. Here, the reactivity depends on the Z-group (protecting group) of the starting amides. Under the same reaction conditions, some sulfonamides were treated with (diacetoxyiodo)benzene and iodine in the presence of aromatics to give the corresponding N-arylated amides. These reactions proceed through the intramolecular and intermolecular amidations onto aromatic rings via the sulfonamidyl radicals formed.

Various N-alkylsulfonamides were easily dealkylated to give the corresponding free sulfonamides in moderate to good yields in the presence of (diacetoxyiodo)benzene and iodine under ultrasonic irradiation. Application of this methodology to various AT-protected alkylamines with sulfonyl, phosphonyl, and acyl groups was carried out, and the oxidative conversion occurred only in N-sulfonyl-protected phenylalkylamines to give the corresponding aldehydes together with free sulfonamides in moderate to good yields.
