YieldReaction ConditionsOperation in experiment
With sodium hydroxide; sodium sulfite; In dichloromethane; water; A mixture containing <strong>[10133-22-9]5-bromomethylbenzo[b]thiophene</strong> (40 g), tetra-n-butylammonium hydrogen sulfate (135 g), sodium hydroxide (14 g), sodium sulfite (45 g), dichloromethane (300 ml), and water (300 ml) was stirred vigorously overnight. The organic layer was dried (MgSO4), evaporated, dissolved in THP (130 ml), re-evaporated, and dissolved again in THF (130 ml). Addition of ether (200 ml) gave the crystalline subtitle compound containing an equimolar amount of tetra-n-butylammonium bromide (132 g).

YieldReaction ConditionsOperation in experiment
With thionyl chloride; sulfuric acid; calcium chloride; sodium hydrogencarbonate; In diethyl ether; ethanol; dichloromethane; benzene; B) (2R)-2-(4-isobutylphenyl)-propanal <strong>[51146-57-7](2R)-2-(4-isobutylphenyl)-propanoic acid</strong> (41.7 g) is added to benzene (40 ml) and thionyl chloride (29.3 ml). This solution is refluxed for 4 hours. In vacuo evaporation of benzene and of non-reacted thionyl chloride leaves a residue which is taken up many times with benzene followed by evaporation in order to completly remove thionyl chloride. (2R)-2-(4-isobutylphenyl)-propanoyl chloride is so obtained as a colourless oil; yield, 45.8 g. An aliquot of this chloride (24.5 g; 0.109 moles) is added dropwise to methyl alcohol (100 ml) under stirring at 10°C. This mixture is allowed to stand at room temperature for 48 hours and then is evaporated to dryness. The residue is taken up with ethyl ether and washed with a 5percent aqueous solution of sodium bicarbonate. The ethereal solution is dried and evaporated to dryness. Methyl (2R)-2-(4-isobutylphenyl)-propanoare is so obtained. Yield, 23.8 g. An aliquot of this ester (23.5 g; 0.106 moles) is dissolved in anhydrous ethyl alcohol (150 ml). To this solution, sodium hydride (5.2 g; 0.138 moles) and calcium chloride are added portionwise while keeping the reaction mixture under stirring at -20°C and in nitrogen atmosphere. This reaction mixture is filtered to discharge the inorganic salt and the filtrate is evaporated to dryness under reduced pressure. The oily residue is dissolved in ethyl ether and this solution is washed with water till neutral. The organic phase is dried on sodium sulfate and then evaporated to dryness. (2R)-2-(4-isobutylphenyl)-propane-1-ol (19.5 g; 95.7percent) is so obtained. An aliquot of this alcohol (18 g; 0.094 moles) is dissolved in methylene chloride (270 ml). This solution is shaked for 10 minutes in a separatory funnel together with a 3M solution of sulfuric acid containing sodium bichromate dihydrate (8.48 g; 0.028 moles) and tetrabutylammonium acid sulfate (3.17 g; 0.009 moles). The organic phase is separated, washed, dried on sodium sulfate and evaporated to dryness under reduced pressure. The desired aldehyde is so obtained as a green oil. Yield, 17.54 g.

YieldReaction ConditionsOperation in experiment
With sodium hydroxide; In dichloromethane; Example 1 Preparation of O-Bis(Boc)-2-Methylene-1,3-Propanediol (Compound of formula II, wherein R11 is hydrogen and R1 is tert-butyl) To a solution of di-tert-butyl dicarbonate (6.6 kg) in methylene chloride (15.0 L, 15 volumes) was added <strong>[3513-81-3]2-methylene-1,3-propanediol</strong> (1.00 kg) and phase transfer catalyst tetrabutylammonium hydrogensulfate (0.641 kg). The resulting reaction mixture was then agitated vigorously at about 15° C. while adding over a 2 hr period, 6M aqueous sodium hydroxide solution (13.2 L) and controlling the temperature between 25 to 30° C. The resulting two-phase reaction mixture was subsequently agitated for a period of 2-3 hrs at 25° C. The aqueous layer was discarded and additional phase transfer catalyst tetrabutylammonium hydrogensulfate (0.064 kg, 10percent of the initial amount), di-tert-butyl dicarbonate (0.66 kg, 10percent of the initial amount), and methylene chloride (2.0 L, 2 volumes) was added to the remaining organic reaction mixture. To the reaction mixture was also added 6M aqueous sodium hydroxide solution (1.32 L, 10percent of the initial amount) over a period of about 0.5 to 1 hr, while controlling the temperature between 25 to 30° C. The resulting two-phase reaction mixture was then agitated at about 25° C. for additional 3 to 4 hr. Allowing more than 3 hrs of agitation time is often required to complete the hydrolysis of the excess di-tert-butyl dicarbonate. The aqueous layer was discarded. The resulting organic phase was washed with water (3*8.0 L), diluted with EtOAc (6 L, 6 volumes), and distilled to an oil foam with quantitative yield. 1H (500 MHz, CDCl3) delta 5.15, 4.98, 4.79, 4.68, 4.68, 4.33, 4.31, 3.89, 3.77, 3.67, 3.45, 3.35, 3.19, 2.88, 2.78, 2.74, 2.42, 2.17, 2.11, 2.06, 1.95, 1.72, 1.66, 1.51, 1.48, 1.43, 1.34, 1.27, 1.19, 1.19, 1.18, 1.14, 1.13, 1.11, 0.95, 0.85
