<p>There is disclosed a novel microbial bioconversion process for the synthesis of a trans-hydroxy sulfone intermediate, which is the precursor to topical carbonic anhydrase inhibitors (TCAI's). TCAI's are effective in the treatment of glaucoma and ocular hypertension. The bioconversion process is carried out in the presence of the microorganism Rhodotorula rubra, or Rhodotorula piliminae and results in a trans-hydroxy sulfone which exhibits a diastereomeric excess of greater than 95 %.</p> |
