Scope of the direct trimerisation to C₃-symmetric cyclotribenzylene derivatives

ABSTRACT

The scope of the trimerisation reaction of 3-substituted benzyl alcohols was explored. Several C₃-symmetric cyclotribenzylene derivatives were obtained in preparative useful yields in one step and applied to the short synthesis (one or two steps) of two CTB derivatives, so far only accessible in six or seven linear steps.
