Sažetak
The title compound was synthesized in the following way:
Reforinatsky condensation ·of ethyl a -bromo-iso-valerate with
acetone and zinc to ethyl 3-hydroxy-2-iso-propyl-3-methyl-butyrate
(1), dehydration to the mixture of ethyl 2-iso-propyl-3-methylbuten-(
3)-oate (II) and 2-iso-propyl-3-methyl-buten-(2)-oate (IV),
and lithium aluminum hydride reduction to 2-iso-propyl-3-methylbuten-(
3)-ol-(1) (VI). The mixture of esters was hydrolysed to
2-iso-propyl-3-methyl-buten-(3)-oic acid (III) which gave on
reduction with lithium aluminum hydride the same alcohol VI.
Proof of the structure of the acid III was accomplished by means
of chemical and physical methods.
