was also found that higher product yields and enantioselectivities were obtained in the aldol reactions when the aromaticaldehyde contains an electron-withdrawing substituent. The catalysts could be recycled and reused five times without significant drop in product yields and enantioselectivities. In addition, cross product contamination was not found when the recovered G3 catalyst was subsequently
