It is demonstrated that α,α-disubstituted-α-nitroketones are reduced to the corresponding trisubstituted nitro alcohols in good to excellent yield and enantiomeric excess by borane-dimethyl sulfide in the presence of a chiral oxazaborolidine catalyst. Red

The synthesis of 15 blocked 7,8-dihydropteridines is described in which the pyrazine ring is built from a derivative of an α-amino ketone.Three routes to the amino ketones based upon amino acids, nitrosyl chloride addition to alkenes, and nitro alcohols are discussed.The compounds synthesised are inhibitors of 6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase , an enzyme in the pathway leading to dihydrofolate, and the inhibitory potencies of the compounds are discussed in the light of a hypothetical active site model for the enzyme.
