Trialkylsilyloxyallyl cations 2 with a ?-donating methoxy substituent at the allylic termini are generated from nonhalogenated substrates via treatment of 5b-e with Lewis acids. 2 undergoes stereo- and regioselective cycloaddition with furans yielding 2-methoxy-8-oxabicyclo<3.2.1>oct-6-en-3-ones.Cycloadduct 7 is converted to 2-methoxytropone 14 and thus represents an efficient entry into tropolonoid systems.
