Aldol condensation between diethylketone and simple aldehydes using (lpc)2BOTfliPr2NEt in CH,CI, gives syn-adducts in good ee (66-90%) and with high diastereoselectivity (290%). Other chiral dialkylboron triflate reagents examined give lower ees. The aldol condensation reaction of boron enolates, l
