Descrição

Aplicação

Methyl (R)-(-)-3-hydroxy-2-methylpropionate may be used in the preparation of (S)-(4-benzyloxy-3-methylbut-1-ynyl)triethylsilane. It may also be used as a starting material in the total synthesis of (-)-discodermolide, (-)-stemoamide and (-)-stemospironine.

The (R)- and (S)-isomers are bifunctional building blocks for the synthesis of a wide variety of optically active molecules.
