On The Use of Viologen Dyes for Stereospecific Bioreductionch as l,l’-dimethyl-4,4’-bipyridinium cation radical (MV.). Reduced viologens can be regenerated electrochemically or enzymatically with hydrogenases or formate dehydrogenases. Many cells possess enzymes which reduce NAD or NADP at the expense of MV. Such an enzyme, which reduces NAD as well as NADP

Use of Microorganisms for the Resolution of Synthetically Useful Bicyclo[3.2.0]Hept-2-En-6-Onesne was reduced using actively fermenting bakers’ yeast to give the corresponding .-ol and .-ol. In both cases the 5-configuration was prevalent at the newly created chiral centre. The same bicyclic ketone was converted into optically active 6S-.-ol and enantiomerically enriched starting material usi

Application of Microbial Transformations in the Total Synthesis of Natural Productsetol products of high enantiomeric excess. The scope and versatility of this method for a variety of substrates was examined and the integration of selected microbial products in synthetic strategies to various natural products including the trichothecene mycotoxins was illustrated.

Aldolases as Catalysts in Organic Synthesis-specific carbon-carbon bond formation catalyzed by aldolases is one of the most efficient and practical route to common and uncommon sugar derivatives. Detailed studies on the synthetic application of FDP aldolase-catalyzed condensation indicate that enzymatic aldol reactions seem to have genuine v
