Abstract

A process which involves a selective chemical reaction, even if the structure of the substrate suggests numerous possibilities for reactivity, represents an attractive strategy.11 NH-Indole-tethered allenols have diverse reactive sites, at which different transformations (C-cyclization versus O-cyclization versus N-cyclization) can take place. The controlled preparation of a cycle from these multifunctional allenes requires selective catalytic systems. ...
