Synthesis and Reactivity of 1,4‐Ethano‐1,5‐Naphthyridine Derivatives Using Microwave Activation or Flow Chemistry

European Journal of Organic Chemistry, EarlyView.
The design of original disubstituted 3,4‐dihydro‐2H‐1,4‐ethano‐1,5‐naphthyridine derivatives is reported under classical and flow methodologies. The conditions are optimized and a wide range of boronic acids are used to determine the scope and limitations of Suzuki–Miyaura or Chan–Lam reactions. The design of some novel disubstituted 3,4‐dihydro‐2H‐1,4‐

Role of RNA modifications in carcinogenesis and carcinogen damage response

Molecular Carcinogenesis, Volume 62, Issue 1, Page 24-37, January 2023., 2023
Abstract The field of epitranscriptomics encompasses the study of post‐transcriptional RNA modifications and their regulatory enzymes. Among the numerous RNA modifications, N6‐methyladenosine (m6A) has been identified as the most common internal modification of messenger RNA (mRNA).

Synthesis of β‐Hydroxy‐α,α‐Dimethyl Carboxylic Esters via Asymmetric Barbier Reaction

European Journal of Organic Chemistry, EarlyView.
The asymmetric Barbier reaction toward β‐hydroxy‐α,α‐dimethyl carboxylic esters is studied. Utilization of indium and (+)‐cinchonine or (–)‐cinchonidine as chiral additives gives access to both enantiomers. By using different allyl and propargyl bromides 10 different derivatives of the β‐hydroxy‐α,α‐dimethyl carboxylic esters are obtained in up to 81 ...

Recent Advances in the α‐Hydrazination (α‐Amination) of Carbonyl Compounds

European Journal of Organic Chemistry, EarlyView.
In recent years, notable progress has been achieved in the α‐hydrazination (α‐amination) of carbonyl compounds, especially in the direct asymmetric electrophilic α‐hydrazination with dialkyl azodicarboxylates. This review summarizes all the methods that appeared over the past decade, categorized based on the type of the reactive chiral intermediate ...
