The pot residue was partitioned between ethyl ether and water. The organic layer was washed with water and brine, dried over sodium sulfate, and concentrated to give a gum which crystallized when triturated with petroleum ether (boiling point range, 30-60 C.). The solid was collected by filtration and recrystallized from isopropyl ether to yield 27.2 g (67%) of off-white solid, mp 73-75 C. (lit1 mp 77 C.). 1 W. Bradley and J.

83% | With palladium 10% on activated carbon; oxygen; sodium acetate; potassium iodide; In 1,2-dimethoxyethane; at 100℃; under 10343.2 Torr; for 3h;Autoclave; Inert atmosphere; | General procedure: In a 100 mL stainless steel autoclave, diol (5mmol), catalyst (10 % Pd/C, 0.5 mol %), KI (0.09 mmol), base (1.25 mmol),solvent (10 mL) were added. The autoclave was closed, flushed with nitrogen,pressurized with O2 (33 psi) and CO (167 psi) and reaction mixturewas stirred with a mechanical starrer (520 rpm) at desired temperature forappropriate time period. After completion of reaction, the reactor was thencooled to room temperature, degassed carefully and opened. The reaction mixturewas filtered and the solvent was evaporated under vacuum. The reaction mixturewas analyzed by GC analysis (Perkin-Elmer, Clarus 400) equipped with a flameionization detector (FID) and a capillary column (Elite-1, 30 m × 0.32 mm ×0.25 mum). Purification of residue was carried out by column chromatography(silica gel 100-200 mesh, petroleum ether/ethyl acetate) to afford thecorresponding products in good to excellent yield. The prepared compounds werecharacterized by 1H NMR (Varian 200 MHz NMR Spectrometer), 13CNMR spectra (50 MHz) and GC-MS (Shimadzu GC-MS QP 2010) (Rtx-17, 30 m × 25mmID,film thickness 0.25 mum df) (column flow- 2 mL/min, 80 C to 240 C at 10/min.rise.) which were consistent with those reported in the literature |

The reaction was stirred overnight (16 h) at room temperature and quenched by adding water. Volatiles were removed by an oil-free rotary evaporator at 60° C for 20 minutes. The corresponding TBDMS ether was extracted with ethyl acetate. The organic phase was combined, washed with 4x20 ml water and dried with Na2SO4.The corresponding mono- and di-TBDMS ether was obtained in nearly quantitative yield after removing the solvent by rotary-evaporation at 60° C for 1 h. |
