2,4-Dimethoxybenzaldehyde (DMBA) is a reagent used to specifically quantify phlorotannins. This product reacts specifically with 1,3-and 1,3,5-substituted phenols (e.g., phlorotannins) to form a colored product. [1]
The aza-Henry reaction is also used to produce nitroamines and can be a reliable synthetic route for the synthesis of vicinal diamines. [13] Perhaps one of the most synthetically useful modifications to the Henry reaction is the use of an organocatalyst. [2] [12] [14] The catalytic cycle is shown below. Henry reaction synthetic scheme
2,4-Dihydroxybenzaldehyde or β-resorcylaldehyde is a phenolic aldehyde, a chemical compound with the formula C 7 H 6 O 3. It is an isomer of protocatechuic aldehyde (3,4-dihydroxybenzaldehyde). References
The term aldol condensation is also commonly used, especially in biochemistry, to refer to just the first (addition) stage of the process—the aldol reaction itself—as catalyzed by aldolases. However, the first step is formally an addition reaction rather than a condensation reaction because it does not involve the loss of a small molecule.
2,4-Dimethoxybenzaldehyde, a reagent used to specifically quantify phlorotannins; para-Dimethylaminobenzaldehyde, a reagent used in Ehrlich's reagent and Kovac's reagent; 7,12-Dimethylbenz(a)anthracene, an immunosuppressant and powerful laboratory carcinogen; 1,3-Dimethylbutylamine, a designer stimulant sometimes found in dietary supplements
βk-2C-B is a designer drug, more specifically it is the beta keto analogue of the controlled substance 2C-B (2,5-dimethoxy-4-bromophenethylamine) which was first synthesized by Alexander Shulgin. It is unknown who first synthesized βk-2C-B, but it first appeared on the market mid-2013 as a recreational drug. [ 1 ]
This reaction is an important approach to the formation of carbon-carbon bonds in organic molecules containing ring systems. As an example, under strong basic conditions (e.g. sodium hydroxide), hexane-2,5-dione (compound A in Figure 1) can cyclize via intramolecular aldol reaction to form the 3-methylcyclopent-2-en-1-one (compound B).
