Formal [3+3]- and [3+2]-cycloadditions of allylsilanes with benzylic cations
摘要:
Allylsilanes serve as three-carbon dipole equivalents for the formation of tetrahydronaphthalenes via Lewis-acid promoted formal [3+3]-cycloadditions with benzylic cations. A competing [3+2]-pathway resulted in the formation of dihydro(1H)indenes. Both quinone methides and benzylic alcohols were used as precursors to the benzylic cations.
