描述

一般說明

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.

應用

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.
