The asymmetric synthesis of (+)-sitophilure, the natural form of the aggregation pheromone of Sitophilus oryzae L. and Sitophilus zeamais M.

Journal of the Brazilian Chemical Society, 1999
The asymmetric synthesis of (+)-sitophilure, the aggregation pheromone of Sitophilus oryzae L. and Sitophilus zeamais M., was carried out in 12 steps, 18% overall yield and 82% enantiomeric excess from the enzymatic reduction of methyl 3-oxopentanoate ...

Chiral thiols. Synthesis and enantiomeric excess determination

, 1987
Chiral thiols are a class of chira compounds, which is gaining mone and nore attention the last decenniun. Especially α-mercaptocarboxylic acids are frequently found as a structunal unit in (biologically) important products. As a consequence, many synthetic analoga or derivatives of these natural products, but also other organosulfur compounds, have ...
