Abstract:
The palladium-catalyzed direct C-H olefination of unprotected uridine, 2'-deoxyuridine, uridine monophosphate, and uridine analogues are described here. This protocol provides an efficient, atom-economical, and environmentally friendly method for the introduction of an alkenyl group at the C5 position of the uracil without pre-functionalization. A series of C5-alkenylated uridine analogues, including some biologically significant compounds and potential pharmaceutical candidates, were synthesized with exposed hydroxyl groups on the ribose. © 2023 Wiley Periodicals LLC. Basic Protocol 1: The reaction of uridine, 2'-deoxyuridine, and sofosbuvir for the C-H olefination with methyl acrylate Basic Protocol 2: The reaction of uridine and 2'-deoxyuridine for the C-H olefination with styrene.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.

Acid-Catalyzed α-Halogenation of Aldehydes and Ketones
In the first step of the mechanism, the acid protonates the carbonyl oxygen resulting in a resonance-stabilized cation, which subsequently loses an α-hydrogen to form an enol tautomer. The C=C bond in an enol is highly nucleophilic because of the electron-donating nature of the –OH group. Consequently, the double bond attacks an electrophilic halogen to form a...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
