The title reaction, incorporating two biodynamic hetero- cyclic moieties,14±17 through the spiro carbon atom appeared interesting in view of the broad spectrum of bioactivity associated with sulfur-containing heterocyclic systems,19,21 along with the presence of different reaction sites, which may lead to the formation of variety of products. The role of fluorine and perfluoro groups in indole chemistry is also noteworthy as compared with their non-fluorinated ...
