Microbial Asymmetric Catalysis—Enantioselective Reduction of Ketones [New Synthetic Methods (45)]

Abstract: Microbial asymmetric reduction of ketones is a method widely used for the preparation of chiral alcohols. The present progress report deals with the basic concepts that govern enantioselectivity of enzymes and intact cells. Strategies to control the stereochemical course of microbial reductions of carbonyl compounds and the relationship of substrate structure to enantioselectivity are considered.

“…The biotransformations involved in drug metabolism in microorganisms are often hydrolysis, reduction, oxidation, and isomerization reactions (36). For the biotransformation of GPS by P. crustosum 2T01Y01, deglycosylation by the ␤-glucosidase that exists in the fungus might be the initiation step.…”

“…na presença de um ligante quiral derivado do ácido tartárico complexado com Ti(OPr i ) 4 40 . No contexto da biocatálise, cabe ressaltar que as reações enzimáticas promovem uma série de reações em substratos pró-quirais, tais como: reduções de carbonilas (na presença dos cofatores NADH ou NADPH, que são os agentes redutores) 41 , oxidações de álcoois e de anéis aromáticos 42 e hidrólise de ésteres 43,44 . Algumas dificuldades maiores se impõem quanto ao uso de catalisadores quirais em síntese assimétrica: uma é devida ao número até hoje restrito de reações estudadas 35b .…”

“…In the framework of (outer sphere) electron transfer t h e~r y~.~ such effects are reflected in the values of k,(s-') and K O (M-I) of the diastereomeric reactions, the former being the unimolecular rate-constant of the electron transfer step and the latter being the equilibrium quotient for the formation of precursor complexes. Obviously, this holds true for any bimolecular process between optically active compounds 5, 6 when the second-order specific rate can be factorized into constants similar to the above.…”
