摘要:
A concise synthesis of 3-dimethyl(phenyl)silyl-5-oxo-hexanoic acid 1, the precursor for a solid supported beta-silylethanol anchoring group has been achieved from ethyl 2-ethoxycarbonyl-3-dimethyl(phenyl)silyl-2-propenoate 2 featuring amino acid catalysed Michael addition of acetone as the key step.
