Anhydrous zinc chloride (0.066 g, 0.48 mmol, sodium methoxide (0.078 g, 1.5 mmol, and (R,R)-3 (0.301 g, 0.48 mmol) were suspended into a 2:1 mixture of methylene chloride/ethanol (15 mL) and stirred for 16 h. The reaction mixture was concentrated and filtered to give a yellow solid that was subsequently dissolved into THF (20 mL) and filtered to remove fine insoluble solids. The clear filtrate was stirred for 2 h, resulting in the formation of a yellow precipitate, which was collected and washed consecutively with THF (5 mL) and ethanol (5 mL) to afford (R,R)-4 (0.177 g, 53, yield, Anal.
