일반 설명
Sodium bis(trimethylsilyl)amide solution (NaHMDS) is widely used as a strong base in organic synthesis for deprotonation reactions and base-catalyzed reactions. It is also involved in the generation of enolates, Wittig reagents and carbenes.
애플리케이션
NaHMDS can be used as a base:
- In the synthesis of N-boc-1-amino-1,3-diene derivatives from N-boc-1-amino-4-methoxy-2-alkenes via 1,4-elimination reactions.
- To deprotonate alkyl or aryl ketones to generate enolate derivatives by hydroxylation reaction.
- In the enantioselective synthesis of 1,2-amino alcohols by the reaction between various nitroalkanes and aldehydes via nitroaldol reaction promoted by bimetallic heterogeneous catalyst.
포장
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
