Aldol Condensation of Aldehydes and Ketones over Solid Base Catalysts
Introduction Industrially condensation reactions are of great importance in the production of a number of key compounds. These include 2-ethyl hexanol, methyl isobutyl ketone (MIBK) and Guerbet alcohols. Over 1.5 million tonnes of these chemicals are produced worldwide every year using homogeneous bases such as NaOH and Ca(OH)2. It has been estimated for these compounds that 30% of the selling ...
متن کاملHighly Diastereoselective Aldol Reactions of Chiral Methyl Ketones
Diastereoselective aldol additions have emerged as one of the most efficient and versatile methods available for preparing a wide range of optically active compounds.l Very high diastereoselectivities have been reported for aldol reactiona involving chiral enolates derived from a-ethylor higher alkyl-substituted ketone derivatives. By contrast, relatively few examples of highly diastereoselecti...
متن کاملEnantioselectivity in the boron aldol reactions of methyl ketones.
DFT computed transition states quantitatively explain the surprising stereochemical outcome of unsubstituted enolborinates in diastereoselective and enantioselective boron aldol reactions.
متن کاملOrganic Synthesis: Aldol Condensation Reaction
In an "aldol addition" reaction an enol or enolate of an aldehyde or ketone reacts with a second aldehyde or ketone forming a new carbon-carbon bond which makes the aldol reaction an important reaction for organic synthesis. Originally, the aldol reaction used ethanal (see below) and therefore the product contained both an aldehyde and an alcohol functional group; thus it became known as the al...
