Reaction Conditions:

with 2,2,6,6-tetramethyl-piperidine;n-butyllithium in tetrahydrofuran;hexane at -20 - 20; for 16 h;Inert atmosphere;

Steps:

General procedure for the deprotection of 1,3-dioxolanes promoted by lithium 2,2,6,6-tetramethylpiperidide (Table 2 and Table 3)
General procedure: To a solution of 2,2,6,6-tetramethylpiperidine (TMP) (0.34 mL, 2.00 mmol, 4.0 equiv.) in THF (4 mL) was added n-BuLi (2.4 M in hexane, 0.83 mL, 2.00 mmol, 4.0 equiv.) at -20 or 0 . After stirring for 30 min, a solution of compound 1 or compound 4 (0.50 mmol, 1.0 equiv.) in THF (1 mL) was added. The resulting mixture was stirred before the completion of the reaction (monitored by TLC). Then the reaction mixture was poured into saturated NH₄Cl solution (2.5 mL) at 0 and diluted with H₂O (5 mL). The layers of the resulting mixture were separated and the aqueous layer was extracted with Et₂O (4 × 15 mL). The combined organic layers were dried over Na₂SO₄, filtered and concentrated under reduced pressure. The residue was purified by flash column chromatography on silica gel to afford products.
