Biotransformation of organic sulfides. Part 6. Formation of chiral para-substituted benzyl methyl sulfoxides by Helminthosporium species NRRL 4671
摘要:
The fungus Helminthosporium species NRRL 4671 has been used for the biotransformation of a series of para-substituted benzyl sulfides with substituent groups consisting of trifluoromethyl, halo, hydroxy, methoxy, acetoxy, nitro, cyano, amino, acetamido, acyl and carboxylic acid units. In all cases, sulfoxide formation occurred in good yield and with predominant (S) chirality at the sulfur position. A minor amount of sulfone product was also obtained from the halo- and methoxy-substituted substrates.
