    • General procedure for the reaction of triflate 5 with styrene oxide (6, In a Schlenk tube equipped with a septum and a magnetic stirring bar, a mixture of triflate 5 (242 μL, 1.00 mmol, styrene oxide (6, 228 μL, 2.00 mmol) and CsF (304 mg, 2.00 mmol) was stirred in MeCN (15 mL) for 24 h. The resulting mixture was concentrated under reduced pressure and the residue was purifed by column chromatography (SiO2; CH2Cl2-hexane, 1:99 to 50:50) to afford compounds 7 and 9-12. All of the products gave satisfactory NMR (1H, 13C) and MS.
