Abstract
Abstract Treatment of N -methoxycarbonyl C -carboxylate ester derivatives of S -methyl- l -cysteine by chloroperoxidase (CPO)/hydrogen peroxide resulted in oxidation at sulfur to produce the ( R S ) sulfoxide in moderate to high diastereomeric excess (DE). The ( S S ) natural product sulfoxide chondrine was obtained via biotransformation of the N -t.boc derivative of l -4-S-morpholine-2-carboxylic acid using Beauveria bassiana or Beauveria caledonica .
