General description

Chloroacetone undergoes direct aldol reaction with 4-nitrobenzaldehyde catalyzed by L-proline amides. It reacts with carboxylic acids to form ester derivatives.

Application

Chloroacetone was used in microbial asymmetric reduction of chloracetone to synthesize chiral 1,2-epoxy propane. It was used in analysis of acids by gas chromatography. It was also used in the syntheis of methylthiazole derivatives by reacting with 1-((3-(naphtho[2,1-b]furan-2-yl)-1-phenyl-1H-pyrazol-4-yl) methylene)-2-phenylhydrazone.

Vilsmeier formylation of 2-(1-phenylhydrazonoethyl)naphtho[2,1-b]furan (2) gave 3-naphtho[2,1-b]furan-2-yl-1-phenyl-1H-pyrazole-4-carbaldehyde (3), which was reacted with C- and N-nucleophiles to afford naphthofuranpyrazol derivatives 4-8. Treatment of 2-[(3-(naphtho[2,1-b]furan-2-yl)-1-phenyl-1H-pyrazol-4-yl)methylene]-malononitrile (4a) with reactants having active hydrogen and Et₃N gave the corresponding pyrazoline, pyran and chromene addition product
