Recently, we have developed modular approach to racemic [6]helicenes and 2-aza[6]helicenes based on double cycloisomerization of biarylnaphthalenes bearing two alkynyl chains.[1] In pursuit of our previous investigations in this field, we describe an alternative approach to [8]helicene-like molecules based on a PtClx and Hg2+ catalyzed tandem cycloisomerization reaction of naphthalene tetraynes. Exploration of their cycloisomerization reaction and finding its scopes will be discussed herein.
