YieldReaction ConditionsOperation in experiment
44% With water In neat (no solvent) at 23℃; Sealed tube A 5 mL round-bottomed flask equipped with a stir bar and plastic cap was charged with oligomeric cyclic (R,R)-(salen)Co(III) triflate 4a (n=1–2) (3.1 mg, contained 9percent toluene by mass, 0.0035 mmol Co) and placed in a room temperature water bath. (±)-Methyl glycidate ((±)-S20) (1 mL, 11.4 mmol) was added followed immediately by H2O (122.5 μL, 6.80 mmol). The reaction was then stirred at room temperature. H2O had completely dissolved by 5 min; catalyst by 9 min. Aliquots were removed periodically, diluted with CH2Cl2, and filtered through a plug of silica to remove product diol. Ee was then determined by chiral GC analysis. Conversions were determined by taking a separate aliquot, diluting with CDCl3, and comparing starting epoxide and product diol 1H NMR integration values.
