Trimethylsilyl N-(trimethylsilyl)acetimidate: A Versatile Reagent for Organic Synthesis

Trimethylsilyl N-(trimethylsilyl)acetimidate, also known as Evonik Degussa Dynasylan BSA or N,O-Bis(trimethylsilyl)acetamide, is a versatile reagent widely used in organic synthesis. INNO SPECIALTY CHEMICALS is the leading manufacturer and supplier of this product in China.

This article will provide an overview of the properties and applications of trimethylsilyl N-(trimethylsilyl)acetimidate in organic synthesis. We will discuss its use as a reagent for the protection of functional groups, as a catalyst for a variety of reactions, and as a precursor for the synthesis of various organic compounds.

Properties of Trimethylsilyl N-(trimethylsilyl)acetimidate

Trimethylsilyl N-(trimethylsilyl)acetimidate is a colorless to yellow liquid with a boiling point of 105-106°C. It is soluble in organic solvents such as dichloromethane, ether, and tetrahydrofuran. The reagent is stable under normal conditions, but it should be stored in a cool, dry place away from sources of heat and moisture.

Applications of Trimethylsilyl N-(trimethylsilyl)acetimidate

Protection of Functional Groups

Trimethylsilyl N-(trimethylsilyl)acetimidate is commonly used as a reagent for the protection of various functional groups in organic synthesis. It can protect alcohols, amines, and carboxylic acids by forming trimethylsilyl ethers, trimethylsilyl amines, and trimethylsilyl esters, respectively. These protective groups can be removed under mild conditions using various reagents, such as tetrabutylammonium fluoride (TBAF).

Catalyst for Reactions

Trimethylsilyl N-(trimethylsilyl)acetimidate is also used as a catalyst for a variety of reactions, including the Mukaiyama aldol reaction, the Baylis-Hillman reaction, and the Michael addition. In these reactions, trimethylsilyl N-(trimethylsilyl)acetimidate acts as a Lewis acid catalyst, promoting the formation of new carbon-carbon bonds.

Precursor for Organic Synthesis

Trimethylsilyl N-(trimethylsilyl)acetimidate is a useful precursor for the synthesis of various organic compounds. It can be used to prepare α,β-unsaturated ketones, which are important intermediates in the synthesis of natural products and pharmaceuticals. It can also be used to synthesize α-amino acids, which are building blocks for peptides and proteins.
