Reaction Steps

Preferably in the claimed method the contacting of the hydantoin with a D-hydantoinase is carried out under conditions permitting the simultaneous epimerization of the chiral center at C-5 of the hydantoin. As discussed further below, the simultaneous epimerization permits the reaction to be carried out to substantial completion so that L-isoleucine hydantoin is converted to N-carbamoyl-D-allo-isoleucine. The N-carbamoyl-D-allo-isoleucine is then decarbamoylated to produce D-allo-isoleucine.
