The reaction mixture was then cooled in an ice/H20 bath, MeCN (120 mL) and H20 (150 mL) were added followed by ruthenium(III) chloride (0.035 g, 0.166 mmol). Sodium periodate (53.4 g, 250 mmol) was then added slowly portion wise over 30 min. The resulting biphasic brown mixture was stirred vigorously while allowed to reach rt for a period of 1.5 h (internal temperature never increased above rt). TLC (50% EtOAc in heptanes) showed complete conversion. The crude mixture was then poured into ice H20 and extracted twice with 300 mL of Et20.

A 50 mL stainless steel autoclave was charged with RuCl[(S,S)-Tsdpen](p-cymene) (0.95 mg, 0.0015 mmol) and NaClO4 (9.2 mg, 0.075 mmol) under argon. Then 2,3-butanedione (129 mg, 1.5 mmol) and methanol (3.0 mL) were added thereto. After pressurization with hydrogen, substitution was conducted five times. Hydrogen was charged to 50 atm to initiate reaction. After stirring for 18 hours at 30C, the reaction pressure was reduced to normal. The product was analyzed by 1H-NMR and HPLC reporting synthesis of (S,S)-2,3-butanediol in yield of 47%. |
