Typical Experimental Procedure To a CH2Cl2 solution (2 mL/mmol of 3) of 3 (1.5 mmol) and of 1,1,3,3-tetramethoxypropane (1.0 mmol) was added TMSOTf(0.1 mmol) at -78 °C. The solution was allowed to warm to 20 °C within 20 h. To the solution was added a diluted aq solution of HCl (15 mL, The organic and the aqueous layer were separated, and the latter was extracted with CH2Cl2 (3 × 15 mL, The combined organic layers were dried (Na2SO 4, filtered, and the filtrate was concentrated in vacuo. The residue was purified by chromatography. Methyl 2-(Phenylthio)benzoate (5a) Starting with 1,1,3,3-tetramethoxypropane (0.33 mL, 2.0 mmol, 3a (843 mg, 3.0 mmol, TMSOTf (0.036 mL, 0.2 mmol, and CH2Cl2 (4 mL, 5a was isolated as a highly viscous colourless oil (275 mg, 53, 1H NMR (250 MHz, CDCl3, δ, 3.66 s, 3 H, OCH 3
