A Rapid and Efficient Synthesis of a Bifunctional β‐Silylketone, Precursor for a Solid Supported β‐Silylethanol Anchoring Group

Abstract

A concise synthesis of 3‐dimethyl(phenyl)silyl‐5‐oxo‐hexanoic acid 1, the precursor for a solid supported β‐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.

Keywords:

• β‐Silylketone
• Michael addition
• Amino acid
• Catalysis
