General description
3-Chloro-2-butanone reacts with 1,4-dianion of acetophenone N-ethoxycarbonylhydrazone to yield pyrazoline derivatives.
Application
3-Chloro-2-butanone was used in production of chiral alcohols from acetophenone derivatives, β-ketoesters and N-Boc-3-pyrrolidinone by recombinant E. coli cells. It was used in the synthesis of carbene precursor, 3-aryl-4,5-dimethylthiazolium chloride.

A new family of ruthenium-based olefin metathesis catalysts bearing a series of thiazole-2-ylidene ligands has been prepared. These complexes are readily accessible in one step from commercially available (PCy3)2Cl2Ru=CHPh or (PCy3)Cl2Ru=CH(o-iPrO-Ph) and have been fully characterized. The X-ray crystal structures

Phenylacetaldehyde reductase (PAR) produced by styrene-assimilating Corynebacterium strain ST-10 was used to synthesize chiral alcohols. This enzyme with a broad substrate range reduced various prochiral aromatic ketones and beta-ketoesters to yield optically active secondary alcohols with an enantiomeric purity of
