✦ Synopsis

Intramolecular condensation of immonium ions with allylsilanes in aqueous tetrahydrofuran at ambient temperature gives rise to five, six, seven, and eight-membered rings containing nitrogen.

A previous report from our laboratory has demonstrated that simple immonium ions, generated & situ under Mannich-like conditions, upon exposure to allylsilanes in the presence of excess --
