Studies of amine oxide rearrangement: an unusual product from the reaction of 4-[N-alkylanilion]but-2-yn-1-ol with m-chloroperoxybenzoic acid
Abstract
Treatment of a dilute solution of 4-[N-methylanilino]but-2-yn-1-ol 1 with MCPBA in chloroform/dichloromethane/benzene gives a symmetrical ten-membered cyclic bisether 5 containing two indole moieties in 56% yield.
