Abstract

The Claisen rearrangement of 3-oxy-2-allyloxyindoles through base-induced enolization of 2-allyloxyindolin-3-ones was investigated. This rearrangement reaction proceeded smoothly at low temperature and showed intriguing diastereoselectivity that did not depend on the initial olefin geometry.

Key words

diastereoselectivity - heterocycles - indoles - rearrangement - solvent effects

  • 14 Generally, α-allyloxy ketones undergo [2,3]-Wittig rearrangement under basic conditions. In contrast, it is interesting to note that our reaction occurs with [3,3]-Claisen rearrangement via enolate anion driven by aromatization stabilization. See also: Takahashi O. Maeda T. Mikami K.
