Alkylating enzymes

Current Opinion in Chemical Biology, 2013
Chemospecific and regiospecific modifications of natural products by methyl, prenyl, or C-glycosyl moieties are a challenging and cumbersome task in organic synthesis. Because of the availability of an increasing number of stable and selective transferases and cofactor regeneration processes, enzyme-assisted strategies turn out to be promising ...

Alkyl Glucosides

Dermatitis, 2017
Alkyl glucosides are surfactants synthesized through the condensation of long-chain fatty alcohols and glucose, extracted from vegetal, renewable sources. Although available for more than 4 decades, they have been rediscovered in recent years because of their eco-friendly character.

Reductive alkyl–alkyl coupling from isolable nickel–alkyl complexes

Nature
The selective cross-coupling of two alkyl electrophiles to construct complex molecules remains a challenge in organic synthesis1,2. Known reactions are optimized for specific electrophiles and are not amenable to interchangeably varying electrophilic substrates that are sourced from common alkyl building blocks, such as amines, carboxylic acids and ...

Alkyl Isosteres

Journal of the American Chemical Society, 2018
By substituting an ER3- unit (E = Group 13 element) or E'R3+ (E' = Group 15 element) for CR3 one gets to methyl isosteres, compounds analogous to alkyls and isoelectronic or iso-valence-electronic to them. The substituent charge can be used to stabilize countercharged aromatic systems; some compounds of this type are known.

Alkyl-Dihydroxyacetonephosphate Synthase

Cell Biochemistry and Biophysics, 1997
The initial steps of ether phospholipid biosynthesis take place in peroxisomes. Alkyl-dihydroxyacetonephosphate synthase, the peroxisomal enzyme that actually introduces the ether linkage, has been purified from guinea pig liver in this laboratory.

Alkylation‐Terminated Catellani Reactions Using Alkyl Carbagermatranes

Angewandte Chemie, 2020
AbstractThe Catellani reaction has received substantial attention because it enables rapid multiple derivatization on aromatics. While using alkyl electrophiles to achieve ortho‐alkylation was one of the earliest applications of the Catellani reaction, ipso‐alkylation‐terminated reactions with β‐H‐containing reactants has not been realized to date ...
