Synthesis and catalytic activities of (S)-1-formylpyrrolidine-2-carboxylic acid derivatives for the enantioselective reductions of both a ketone and a ketimine
A series of (S)-1-formylpyrrolidine-2-carboxylic acid derivatives (6a-t) have been synthesised and examined as chiral organocatalysts in the asymmetric reduction of both ketone 2 and ketimine 3. These organic activators afforded good to moderate enantiose
Synthesis of 1-((S)-3-acetylthio-2-methylpropanoyl)-L-pro pyl-L-phenylalanine (alacepril) and one of its active metabolites, the desacetyl derivative (DU-1227)
