Addition-Rearrangement Reactions of N-(Arylsulphonyloxy)amines and 3,4-Dihydro-2H-pyran

Hoffman, Robert V.,Salvador, James M.

, p. 1375 - 1380 (2007/10/02)

A series of N-alkyl-O-(arylsulphonyl)hydroxylamines (NSA) was treated with 3,4-dihydro-2H-pyran (DHP).Acid-catalysed addition to the double bond followed by cationic rearrangement gave cyclic imidates from hydride migration (major) and ring expansion (min
