Recombinantbenzaldehydelyase (BAL), expressed and purified from E. coli strain JM-109, was used to catalyze the condensation of a series of methoxybenzaldehydes and phenylacetaldehyde in the synthesis of α-(R)-hydroxydihydrochalcones. Enantiomerically pure 1-hydroxy-1,3-diphenylpropan-2-ones and o-anisoin were also obtained as products of the BAL reaction. The R absolute configurations of chiral
