Enantioselective Syntheses of (S)- and (R)-3-Hydroxypyrrolidin-2-ones via Lactate Dehydrogenase Catalysed Reductions of 4-Benzyloxycarbonylamino-2-oxobutanoic Acid

The first examples of the BS- and SE-lactate dehydrogenase catalysed reductions of an α-keto acid incorporating a nitrogen containing function in the side chain are described: (S)- and (R)-benzyloxycarbonylamino-2-hydroxybutanoic acids were prepared in good yield and excellent enantioselectivities and were converted to the (S)- and (R)-3-hydroxypyrrolidin-2-ones respectively.

4-O-(2,3,5-Trideoxy-5-amino-α-D-pentofuranosyl)-6-O-aminoglycosyl-1,3-diaminocyclitois, methods for their preparation, pharmaceutical formulations thereof and their use as antibacterial agents

4-O-(2,3,5-Trideoxy-5-amino-α-D-pentofuranosyl)-6-O-aminoglycosyl-1,3-diaminocyclitols and 1-N-substituted derivatives thereof are described together with methods for their preparation and their use as antibacterial agents. Preferred are 1-N-(ω-amino-α-hydroxyalkanoyl)-[4-O-(2,3,5-trideoxy-5-amino-α-D-pentofuranosyl)-6-O-garosaminyl-2-deoxystreptamines], particularly the 1-N-(S-β-amino-α-hydroxypropionyl) derivatives, which are broad spectrum antibacterial agents.
