    • Typical Procedure and Selected Data for Compound 9: In a 10-mL round-bottomed flask under argon, 7 (100 mg, 0.16 mmol) and 4-chlorobenzaldehyde (22 μL, 1.2 equiv) were dissolved in freshly distilled THF (1 mL) at -78°C, then a 1 M solution of LiHMDS in THF (383 μL, 2.4 equiv) was added dropwise over 5 min. Stirring was maintained during 30 min at -78°C and then at r.t. for 1 h. After hydrolysis, the mixture was extracted with EtOAc (3 x 10 mL, dried over Na2SO4, concentrated by rotary evaporation and purified by flash chromatography to afford the desired product (63 mg, 0.115 mmol, yield: 72, yellow liquid; [α] D22 -1 (c, 1, acetone, Rf0.44 (EtOAc-PE, 1:9, 1H NMR (300 MHz, CD3COCD3, δ, 3.89-3.96 (m, 3 H, 2 x H-8, H-6, 4.21-4.26 (m, 1 H, H-7, 4.31 (dd, J, 3.3, 5.7 Hz, 1 H, H-5, 4.61-4.88 m, 6 H, OCH2Ph, 5.25
