The Uses of 3-Hydroxypivalic acid
3-Hydroxy-2,2-dimethylpropionic acid is used as pharmaceutical intermediate.
Reactions
When 3-Hydroxypivalic acid (1r)
was used under standard conditions, the free hydroxyl group was
well tolerated and after conjugated addition, the lactonization took
place smoothly to afford compound 3ra as a single
diastereoisomer (according to 1H- and 13C-NMR)[1].
Tandem decarboxylation-Giese reaction-lactonization
