    • Hydrolysis of the boronate ester was observed in this process that resulted in decreased yield. All the pinacol boronate esters, i.e., 2, 4, 5, and 6, are sufficiently stable to the silica gel flash chromatography conditions that we used, although small amounts of decomposition may occur if a prolonged column chromatography process was applied
