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 excellent functional group compatibility of the Krische allylation combined with the tractability of the allyl acetate pronucleophiles enables the use of allyl donors bearing highly complex nitrogen-rich substituents. [20] insert a caption here. The figure below shows some of the different allyl donors that have been used in the Krische ...
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]
They speak Stieng, a language in the Bahnaric group of the Mon–Khmer languages. Most Stieng live in Bình Phước Province (81,708 in 2009) [ 3 ] of the Southeast region of Vietnam. In Cambodia, they are classified as a group that used to refer to non-Khmer people, under the name Khmer Loeu .
Isomers of BINOL. The Keck asymmetric allylation has many applications to the synthesis of natural products, [1] including (−)-Gloeosporone, [2] Epothilone A, [3] the CD-Subunit of spongistatins, [4] and the C10-C20 Subunit of rhizoxin A, [5] The Keck allylation has also been utilized to form substituted tetrahydropyrans enantioselectively, moieties found in products such as phorboxazole and ...
