Application of crude preparations of leaves from food plants for the formation of cyanohydrins with high enantiomeric excesses

Crude preparations obtained from mamey (Pouteria sapota), capulin (Prunus serotina var. capulli) and peach (Prunus persica) leaves were used to catalyze the enantioselective addition of HCN to a variety of aldehydes. The corresponding cyanohydrins were obtained with high levels of enantioselectivity, comparable with those obtained with other catalysts used for the same purpose.
