Due to the nature of the aldol
condensation reaction employed in the in this study, it is possible that some [alpha]-Ketoacid compounds might interfere during the color formation reaction.
Countless reactions have been performed using a wide range of soluble nucleophiles, including aldol
condensations, Michael additions, homoenolate reactions, pericyclic reactions, and transesterification reactions.
and Michael Additions of Allyls, Enolates, and Enolate Equivalents
products 1-15 were prepared from condensation of 2-formylfuran, 2-formylpyridine and 2-formylthiophene with acetone, acetophenone, 3-methyl-aceto-phenone, [?
The method of obtaining I comprised a two-step process that included aldol
condensation followed by reductive amination via Leuckart reaction.
They describe the manufacture of such different products as nylon, methionine and plexiglas using fundamental aspects of organic chemistry, including chirality, aldol
condensation and esterification.
condensation of the dianion of ethyl acetoacetate with cinnamaldehyde (7) or p-methoxycinnamaldehyde (8) afforded 4-hydroxy-6- ([alpha]-trans-styryl)-5,6-dihydro-2-pyron (9) or 4-hydroxy6-([alpha]-trans-4-methoxystyryl)-5,6-dihydro-2-pyrone (10), followed by methylation with [(C[H.
and Related Processes (Masanori Kawasaki and Hisashi Yamamoto).
Extending the coverage of its predecessor, Modern Aldo Reactions, this reference focuses on the latest developments and offers new tools for use of the aldol
reaction in the development of natural products and pharmaceuticals.
The alkylation of carbon in the ortho and para substitution occurs, however substitution in meta is exclusively not obvious, the phenol reacts with the methanal in the reaction of hydroxymethylation (figure 3) where the condensation aldol
takes place but here the balance of tautomerism is in favour of the form phenol which is most stable due to its aromatic character.
This volume of the series consists of two chapters, on catalytic enantioselective aldol
addition reactions, and benzylic activation and stereochemical control in reactions of tricarbonyl(arene)chromium complexes.
Other projects explore preparative and mechanistic aspects of heterogeneous organic reactions such as Friedel-Crafts alkylation catalyzed by silica gel, aldol
condensation catalyzed by zeolites, ether formation from sterically hindered alcohols through phase-transfer catalysis, and oxidations with solid-supported reagents.
