実験手順: 2,3-Epoxypropyl isopropyl ether (1.16 g.) in several ml. of dry tetrahydrofuran is added to a stirred suspension formed by the addition of 50 mg. of sodium hydride (56% dispersion in mineral oil) to 2.2 g. 8. of n-dodecylthiol in 50 ml. tetrahydrofuran. The mixture is then stirred at 60° C. After approximately 4 hours the solvent is removed from the reaction mixture and 20 ml. of water is added to the residue. The resultant aqueous mixture is extracted with ether and the ether extracts washed with water, dried over magnesium sulfate and evaporated to yield 1-(n-dodecylthio)-3-isopropoxy-2-propanol. formed by the addition of 50 mg After approximately 4 hours the solvent is removed from the reaction mixture and 20 ml of water is added to the residue The resultant aqueous mixture is extracted with ether the ether extracts washed with water dried over magnesium sulfate evaporated

実験手順: 2-(Isopropoxymethyl)oxirane (23.23 g, 25.1 mL, 200 mmol) was dissolved in hexane (20 mL) and placed in reactor. Separately (1.2 g, 20 mmol) of KH was slowly added to (90.1 g, 115 mL, 1.5 Mol) of isopropanol at RT. After deprotonation was complete the solution of potassium isopropoxide in isopropanol was added to the reactor. All operations were performed in a glove box. The reactor was sealed and heated 80° C. for 24 hours. After cooling acetic acid (20 mmols) and ca. 5 g. of powdered talc were added to the reaction mixture followed by filtration through a plug of celite. The solvent was evaporated and the residue distilled under vacuum affording 20.09 g of 1,3-diisopropoxypropan-2-ol. placed in reactor was added to the reactor All operations were performed in a glove box The reactor was sealed followed by filtration through a plug of celite The solvent was evaporated the residue distilled under vacuum
