Benzyl group and derivatives: Benzyl group, benzyl radical, benzyl amine, benzyl bromide, benzyl chloroformate, and benzyl methyl ether. R = heteroatom, alkyl, aryl, allyl etc. or other substituents. In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure R−CH 2 −C 6 H 5.
For example, the amino acid tyrosine could be protected as a benzyl ester on the carboxyl group, a fluorenylmethylenoxy carbamate on the amine group, and a tert-butyl ether on the phenol group. The benzyl ester can be removed by hydrogenolysis, the fluorenylmethylenoxy group (Fmoc) by bases (such as piperidine), and the phenolic tert -butyl ...
Benzyl bromide is an organic compound with the formula C 6 H 5 CH 2 Br. The molecule consists of a benzene ring substituted with a bromomethyl group. It is a colorless liquid with lachrymatory properties.
The Sommelet reaction is an organic reaction in which a benzyl halide is converted to an aldehyde by action of hexamine and water. [1] [2] It is named after the French chemist Marcel Sommelet, who first reported the reaction in 1913. [3] One example, thiophene-2-carboxaldehyde is prepared by the reaction of hexamine with 2-chloromethylthiophene ...
Benzyl bromide is an isomer, which has a bromine substituted for one of the hydrogens of toluene's methyl group, and it is sometimes named α-bromotoluene. Preparation [ edit ]
A photolabile protecting group (PPG; also known as: photoremovable, photosensitive, or photocleavable protecting group) is a chemical modification to a molecule that can be removed with light. PPGs enable high degrees of chemoselectivity as they allow researchers to control spatial, temporal and concentration variables with light.
The Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines.Traditionally, the reaction uses potassium phthalimide. [1] [2] [3] The reaction is named after the German chemist Siegmund Gabriel.
For the action potential to reach the myofibrils, the action potential travels along the transverse tubules (T-tubules) that connects the sarcolemma and center of the fibre. [ 17 ] Later, action potential reaches the sarcoplasmic reticulum which stores the Ca 2+ needed for muscle contraction and causes Ca 2+ to be released from the sarcoplasmic ...
