Biocatalytic and chemical routes to all the stereoisomers of methionine and ethionine sulfoxides
Biotransformations of the N-phthaloyl derivatives of D- and L-methionine and of D- and L-ethionine by Beauveria bassiana ATCC 7159 or Beauveria caledonica ATCC 64970 produce the corresponding (S(s)) sulfoxides in good yield and diastereomeric excess. Pure
