Orthogonal protection is a strategy allowing the specific deprotection of one protective group in a multiply-protected structure. 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.
In organic chemistry, an allyl group is a substituent with the structural formula −CH 2 −HC=CH 2. It consists of a methylene bridge (−CH 2 −) attached to a vinyl group (−CH=CH 2). [1] [2] The name is derived from the scientific name for garlic, Allium sativum. In 1844, Theodor Wertheim isolated an allyl derivative from garlic oil and ...
The troc group is traditionally removed via Zn insertion in the presence of acetic acid, resulting in elimination and decarboxylation. Amine protection – 2,2,2-Trichloroethoxycarbonyl (Troc) [ edit ]

For example, benzyl chloroformate is used to introduce the Cbz (carboxybenzyl) protecting group and fluorenylmethyloxycarbonyl chloride is used to introduce the FMOC protecting group. Chloroformates are popular in the field of chromatography as derivatization agents.

Each allyl group lies in a plane at an angle of about 111.5° to the square formed by the palladium and carbon atoms, and the Pd–C distances are all equal. Its unit cell is monoclinic. [ 1 ]
It is a colorless liquid. The compound consists of a phenyl group attached to an allyl group. Allylbenzene isomerizes to trans-propenylbenzene. [3] In plant biochemistry, the allylbenzene skeleton is the parent (simplest representation) of many phenylpropanoids. Prominent allylbenzenes include eugenol, safrole, and many others. [4]
