Ethyl 3-methyl-2-oxobutyrate Chemical Properties,Usage,Production

Chemical Properties

clear light yellow liquid

Uses

Ethyl dimethylpyruvate is used as an allyl halide reactant in the presence of indium to release hydroxy unsaturated carbonyl compounds. It was also used in the synthesis of (2SR,4SR)-5(S)-(N-Boc)-amino-6-cyclohexyl-4-hydoxy-2-isopropyl hexanoic acid.

Uses

Ethyl 3-methyl-2-oxobutyrate was used in the synthesis of (2SR,4SR)-5(S)-(N-Boc)-amino-6-cyclohexyl-4-hydoxy-2-isopropyl hexanoic acid.

General Description

Ethyl 3-methyl-2-oxobutyrate reacts with a variety of allyl halides in the presence of indium to afford hydroxy unsaturated carbonyl compounds. Conformational behaviour of ethyl 3-methyl-2-oxobutyrate was investigated using solution FTIR in combination with ab initio calculations.
