Substitutedazepanes have flexible ring structures and this conformational diversity is important for their bioactivity. We have shown that a single fluorine atom, when installed diastereoselectively on a model azepane ring, can bias its ring to one major conformation. Here the conformational effects of mono-, di-, and trifluorination, as well as hydroxylation, on substitutedazepanes have been investigated
