Ytterbium triflate is an effective catalyst for the synthesis of either
isopropyl esters or free α-hydroxy-arylacetic acids (mandelic acid derivatives)
from substituted aromatic glyoxals and aryl methyl ketones, respectively. The
environmentally friendly synthesis of mandelic acid derivatives provides
products in excellent yield without any further purification after the usual
workup.
