enzymatic aldol or Claisen condensations other than the presumption that carbon-carbon bond formation is a separate event from the dehydration (Sherman et al., 1991). Tcm C, 1, is an antitumor antibiotic produced by S. glaucescens GLA.0 (Weber et al., 1976). We have previously established the biosynthetic pathway 1 from acetate and
The aldol condensation of ketones with aryl aldehydes to form α,β-unsaturated derivatives is called the Claisen-Schmidt reaction. The success of these mixed aldol reactions is due to two factors. First, aldehydes are more reactive acceptor electrophiles than ketones, and formaldehyde is more reactive than other aldehydes.
Chemicals used, procedure, author comments, data and references for: Aldol condensation of benzaldehyde and acetone.
The term condensation is used to describe a reaction in which two molecules combine to form a larger product with the loss of a molecule of water. The key structural feature of a molecule which might be made by way of an aldol condensation is the carbon-carbon double bond between the alpha and beta carbons of an aldehyde.
Aldol Condensation - β-hydroxyl aldehydes and β-hydroxyl ketones result when aldehydes and ketones with one α-hydrogen undergo reaction with a dilute base as a catalyst. The term Aldol is a combination of aldehydes and alcohol. β- Unsaturated carbonyl compounds are the resultants of Aldol condensation.
