Product Description

 

1. Deprotonation and Formation of Reactive Intermediates
   LDA is used to deprotonate weakly acidic compounds, generating carbanions that can act as nucleophiles in various organic reactions. This is particularly useful for forming kinetic enolates (the thermodynamically less favored isomers) and (hetero-)aromatic carbanions.
2. Carbon-Carbon Bond Formation
   LDA facilitates the formation of carbon-carbon bonds by promoting reactions such as the aldol condensation and α-alkylation of carbonyl compounds. It is also used in the enolization of esters, which is crucial for the synthesis of complex organic molecules.
3. Synthesis of Amino Acids and Ketones
   LDA plays a key role in the synthesis of certain amino acids and their derivatives, as well as in the formation of ketones and other functional groups.
4. Pharmaceutical Applications
   In the pharmaceutical industry, LDA is used to develop novel active pharmaceutical ingredients. For example, it is used in the synthesis of Gemfibrozil, a serum lipid-regulating agent.
5. Polymerization Initiator
   LDA can act as an initiator in the anionic polymerization of monomers such as D,L-lactide and methyl methacrylate.
6. Ortho-Lithiation and Rearrangement Reactions
   LDA is used in ortho-lithiation of arylsulfonyloxazolidinones to prepare N-substituted saccharin analogs and to catalyze Fries rearrangement of aryl carbamates.
7. Isomerization of Allylic Ethers
   LDA promotes the isomerization of allylic ethers to (Z)-propenyl ethers, which are important intermediates in organic synthesis.
