    • General Procedure for the Acylation of Compounds 18 and 28: To a stirred solution of 2,2,6,6-tetramethylpiperidine (TMP, 0.84 mL, 5.00 mmol) in THF (5.50 mL) at -78°C under argon was added n-BuLi (1.60 M in hexanes, 3.70 mL, 5.92 mmol) dropwise. After 15 min the solution was warmed to r.t. and stirred for a further 30 min to give a 0.5 M solution of LTMP. To a stirred solution of 18 or 28 (1.4 mmol) in THF (20 mL) at -78°C under argon was added a solution of LTMP (0.5 M in THF, 4.40 mL, 2.20 mmol) dropwise. After stirring for 1 h, a solution of ester (0.70 mmol) in THF (2 mL) was added dropwise. The reaction mixture was stirred at -78°C for 24 h and quenched with sat. citric acid (20 mL, The organic layer was separated, and the aqueous layer was extracted with CH2Cl2 5 x 50 mL, The combined organic layers were dried with MgSO4 and the solvent was removed in vacuo.
