Step-by-Step Solution1. Definition of Active Alpha Hydrogen Atom: - An active alpha hydrogen atom is a hydrogen atom that is attached to the carbon atom adjacent (alpha carbon) to a carbonyl group (C=O) in a
Provided herein are polymeric α-hydroxy aldehyde or α-hydroxy ketone reagents which can be conjugated to amine-containing compounds to form stable conjugates in a single-step reaction. In selected embodiments, the polymeric reagent itself incorporates an internal proton-abstracting (basic) functional ...

Hydrogenation of the aldehyde group by raising the reaction temperature leads to hydroxycarboxylic esters which may react to form lactones (Scheme 10). As the α-carbon atom possesses the greater negative charge, formation of the α-isomer (56) is possible even if R2 is not a hydrogen atom ...

which Hydrogen will be extracted-H near ketone group(Marked-2) or the ester Adjacent H(marked 1) My approach-In intramolecular Rxns between aldehydes and ketones,Base extracts H from carbon adjacent to ketone(making it a nucleophile) as Carbonyl carbon of aldehyde has more plus character,...
In acid: Equilibrium Amounts • For aldehydes and ketones, the keto form is greatly favored at equilibrium. • An enantiomer with an enolizable hydrogen can form a racemic mixture. Acidity of αHydrogens • pK a for αH of aldehyde or ketone ~20. ...
