## Abstract Protected homopropargyl alcohol (I) is converted into indene derivatives by a new cascade sequence including Sonogashira coupling with aryl iodides (II) or aryl bromides (V), carbopalladative cyclization and Suzuki coupling with aryl boronic acids (III).
Electrophilic 5-endo-trig Cyclizations of 2-Silyl-3-alkenols. A Stereoselective Route to Polysubstituted Tetrahydrofurans. -The scope and limitations of the 5-endo-trig-like cyclization of 9 2-silyl-3-alkenols, e.g. (I), to give tetrahydrofurans, e.g. (III), is investigated. The regioselectivity see
