Exempel på hur man kan använda IMINES i en mening

• In type 3 the substrates are epoxides, notably 2,3-epoxy-alcohols and type 4 concerns the reactions of alpha hydroxyketones and alpha hydroxy imines.
• Also named for Strecker are the Strecker degradation, which involves the conversion of amino acids into imines and then into ketones, and the Strecker sulfite alkylation.
• A variety of pharmaceutical drugs include sydnone imines in their chemical structure including feprosidnine, linsidomine, mesocarb, and molsidomine, among others.
• N-Sulfinyl imines (N-sulfinylimines, sulfinimines, thiooxime S-oxides) are a class of imines bearing a sulfinyl group attached to nitrogen.
• Thus, (E) imines, in which the lone pair and larger imine carbon substituent are cis, tend to give exo products.
• It also efficiently reduces acyl chlorides, anhydrides, α-hydroxylactones, thioesters, and imines at room temperature or below.
• In organic chemistry, a semicarbazone is a derivative of imines formed by a condensation reaction between a ketone or aldehyde and semicarbazide.
• Cyclohexene derivatives, such as imines, epoxides, and halonium ions, react with nucleophiles in a stereoselective fashion, affording trans-diaxial addition products.
• They can be considered a sub-class of imines, being either secondary ketimines or secondary aldimines depending on their structure.
• Molsidomine and linsidomine are sydnone imines, a class of mesoionic heterocyclic aromatic chemical compounds.
• Other functional groups that have been reduced with hydrosilanes include amides, and α,β-unsaturated esters enamines, imines, and azides.
• Examples include reductive amination, carbonyl reduction, nitro compound reduction, the reduction of imines and Schiff bases and debenzylation reactions.
• Compounds containing both a primary amino group and a hydroxyl group bonded to the same carbon atom are rarely stable, as they tend to dehydrate to form imines which polymerise to hexamethylenetetramine.
• Jacobsen has developed catalysts for asymmetric epoxidation, hydrolytic kinetic resolution and desymmetrization of epoxides, asymmetric pericyclic reactions, and asymmetric additions to imines.
• Nitrogen derivates such as amides, nitriles, imines, and most other organonitrogen compounds are reduced to the corresponding amines.
• Aminophosphonates are often prepared by hydrophosphonylation, usually the condensation of imines and phosphorous acid.
• Reactions between aldimines and α-methylene carbonyls are also considered Mannich reactions because these imines form between amines and aldehydes.
• Hydrogenation of imines is complicated by both syn/anti isomerization and tautomerization to enamines, which may be hydrogenated with low enantioselectivity in the presence of a chiral catalyst.
• In organic chemistry, an oxime is an organic compound belonging to the imines, with the general formula , where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime.
• After joining Johns Hopkins University in 1994, Lectka conducted research on new catalytic and asymmetric reactions, along with enantioselective reactions of imines, quinones and amides catalyzed by chiral Lewis acids and nucleophiles; such as catalytic, asymmetric synthesis of β-lactams; and nonnatural α- and β-amino acids.
