Methylketol or 2-methylindole is a mildly toxic and slightly flammable organic compound which occurs as a white solid which turns brown over time. [1] [2] It has chemical formula C 9 H 9 N. [3] Methylketol is used as an intermediate for synthesizing dyes, [4] pigments, [5] optical brighteners, and pharmaceuticals. [6]

Although the synthesis of indole itself is problematic using the Fischer indole synthesis, it is often used to generate indoles substituted in the 2- and/or 3-positions. Indole can still be synthesized, however, using the Fischer indole synthesis by reacting phenylhydrazine with pyruvic acid followed by decarboxylation of the formed indole-2 ...
The initiation factor interacts with the eIF1 and eIF5 factors used for scanning and selection of the start codons. This can create changes in the selection of the factors, binding to different codons. [8] Another important eukaryotic initiation factor, eIF2, binds the tRNA containing methionine to the P site of the small ribosome. The P site ...
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [ 1 ]
The Smith indole synthesis begins by use of two equivalents of an organolithium reagent (as organolithium reagents are very strong bases) to extract a hydrogen from both the alkyl substituent and the nitrogen, resulting in a negative charge on both. The synthesis proceeds with a nucleophilic attack of the carbanion on the electrophilic carbonyl ...
The Fischer indole synthesis is a chemical reaction that produces the aromatic heterocycle indole from a (substituted) phenylhydrazine and an aldehyde or ketone under acidic conditions. [1] [2] The reaction was discovered in 1883 by Emil Fischer. Today antimigraine drugs of the triptan class are often synthesized by this method. The Fischer ...
Methyl groups are added to S, N, O, or C atoms, and are classified by which of these atoms are modified, with O-methyltransferases representing the largest class. The methylated products of these reactions serve a variety of functions, including co-factors, pigments, signalling compounds, and metabolites.
