[a] 0.3 mmol of 2, Zn(BF₄)₂⋅x H₂O (5 mol %) and 1 (1.1 equiv) was reacted in CH₂Cl₂ (0.5 mL) at RT. [b] Yield of isolated product. [c] The ratio of diastereomers was determined by ¹⁹F NMR analysis of the crude reaction mixture. [d] Zn(BF₄)₂⋅x H₂O (10 mol %) in CH₂Cl₂ (0.3 mL) was used. [e] The reaction was performed at 40 °C. Ms=methanesulfonyl, Ns=4-nitrobenzenesulfonyl.
