Exempel på hur man kan använda IMINE i en mening

• In organic chemistry, an imino acid is any molecule that contains both imine (>C=NH) and carboxyl (-C(=O)-OH) functional groups.
• A primary imine in which C is attached to both a hydrocarbyl and a H is called a primary aldimine; a secondary imine with such groups is called a secondary aldimine.
• Schiff bases can be synthesized from an aliphatic or aromatic amine and a carbonyl compound by nucleophilic addition forming a hemiaminal, followed by a dehydration to generate an imine.
• Nucleophilic addition of methylamine to succinaldehyde, followed by loss of water to create an imine.
• The Mannich base is an endproduct in the Mannich reaction, which is nucleophilic addition reaction of a non-enolizable aldehyde and any primary or secondary amine to produce resonance stabilized imine (iminium ion or imine salt).
• This explains the need for an acid catalyst in most cases, as the imine is not electrophilic enough for ring closure but the iminium ion is capable of undergoing the reaction.
• Reductive amination (also known as reductive alkylation) is a form of amination that involves the conversion of a carbonyl group to an amine via an intermediate imine.
• The imine functional group in agmatine then is hydrolysed by agmatine deiminase, releasing ammonia, converting the guanidine group into a urea.
• Thus, (E) imines, in which the lone pair and larger imine carbon substituent are cis, tend to give exo products.
• In Mechanism I, the elimination occurs with imine formation after cyclization; while in Mechanism II, the elimination yields the nitrilium intermediate prior to cyclization.
• The aminopyrimidine ring on TPP acts as a base, once in its imine form, to pull off the C2 proton from TPP to form the nucleophile ylide.
• The reaction depicted in Scheme 2 illustrates the Povarov reaction with an imine and an enamine in the presence of yttrium triflate as the Lewis acid.
• The reaction involves addition of a sulfur ylide to a ketone, aldehyde, imine, or enone to produce the corresponding 3-membered ring.
• This intermediate then fragments to the imine 4a and the saturated cyclohexanone 4b in a non-reversible reaction and both fragments recombine in a condensation reaction to the conjugated imine 5.
• The dialdehyde is then treated with the aromatic diamine to enact an imine condensation to form the macrocyclic core of Texaphyrin.
• For example, the positive ion may be a carbenium, carbonium or acylium ion; the neutral fragment could be an alkene, alkyne, or imine; and the negative fragment could be a tosyl or hydroxyl ion:.
• NAPQI, also known as NAPBQI or N-acetyl-p-benzoquinone imine, is a toxic byproduct produced during the xenobiotic metabolism of the analgesic paracetamol (acetaminophen).
• The first stage of the reaction is basic imine formation by the ketone group and the amine group of morpholine to give an enamine.
• Mesocarb, also known as 3-(β-phenylisopropyl)-N-phenylcarbamoylsydnonimine, is a substituted phenethylamine and amphetamine and a mesoionic sydnone imine.
• In a similar mechanism of aspartate transaminase, the lysine that forms the initial imine to PLP later acts as the base that attacks the tyrosine in transimination.
