Anisyl alcohol (4-methoxybenzyl alcohol) is an organic compound with the chemical formula CH 3 OC 6 H 4 CH 2 OH. [1] It is a colorless liquid that is used as a fragrance and flavorant. It occurs naturally but is produced by reduction of the aldehyde or carboxylic acid. [2] It reacts with hydrogen bromide to give 4-methoxylbenzyl bromide. [3]
Under Corey–Kim conditions allylic and benzylic alcohols have a tendency to evolve to the corresponding allyl and benzyl chlorides unless the alcohol activation is very quickly followed by addition of triethylamine. In fact, Corey–Kim conditions —with no addition of triethylamine— are very efficient for the transformation of allylic and ...
4-Methoxybenzylthiol is an organosulfur compound with the formula CH 3 OC 6 H 4 CH 2 SH. A colorless, odiferous oil, it is a reagent used as a protected thiol . [ 1 ]
Piperonal can be prepared by the oxidative cleavage of isosafrole or by using a multistep sequence from catechol or 1,2-methylenedioxybenzene.Synthesis from the latter chemical is accomplished through a condensation reaction with glyoxylic acid followed by cleaving the resulting α-hydroxy acid with an oxidizing agent.
Chemistry [ edit ] Vanillyl alcohol can be produced by reducing vanillin with sodium borohydride under basic conditions, then quenching using a strong acid such as hydrochloric acid .
Mequinol, MeHQ or 4-methoxyphenol, is an organic compound with the formula CH 3 OC 6 H 4 OH. It is a phenol with a methoxy group in the para position. A colorless solid, it is used in dermatology [ 1 ] and organic chemistry .
The chemical is produced by the Reimer-Tiemann reaction on 4-methoxyphenol with a 79% yield. [1] It reacts with malononitrile to form 2-imino-6-methoxy-2H-1-benzopyran-3-carbonitrile. [2] It can be reduced by sodium borohydride in ethanol to form 2-hydroxy-5-methoxybenzyl alcohol. [3]
These intermediates then react in an aldol condensation to the allyl aldehyde which the hydrogenation catalyst then reduces to the alcohol. [5] Guerbet Reaction Mechanism. The Cannizzaro reaction is a competing reaction when two aldehyde molecules react by disproportionation to form the corresponding alcohol and carboxylic acid.
