Novel Synthesis of 8-Deaza-5,6,7,8-tetrahydroaminopterin Analogues via an Aziridine Intermediate

Molecules, 2012
An efficient method for the construction of the tetrahydrofolate skeleton is described. Starting from pterin analogues and aromatic amines, 8-deaza-5,6,7,8-tetrahydroaminopterin derivatives and the heterocyclic benzoyl isosteres were synthesized via a ...

Aromatic Pummerer‐Promoted Stereospecific Cross‐Coupling of Thiazoles With Boronic Esters

Angewandte Chemie, EarlyView.
A lithiation–borylation–aromatic Pummerer (LiBAP) strategy enables stereospecific, C5‐selective C(sp2)–C(sp3) cross‐coupling of thiazoles with boronic esters. By using exocyclic sulfoxide activation to overcome the low nucleophilicity that frustrates SEAr‐type coupling, the method delivers enantioenriched alkylated thiazoles bearing a versatile C2 ...

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Synthesis, characterization and applications of some novel mordent and heterocyclic disperse dyes on polyester and wool fibers

Orbital: The Electronic Journal of Chemistry, 2012
The novel mordent and disperse heterocyclic dyes were prepared by coupling of various diazo solution of aromatic amines with 1-[(2-butyl-2,3-dihydrobenzofuran-3-yl)]-1-(4-hydroxyphenyl)methanone. The resultant mordent and disperse heterocyclic dyes

Chemical analysis of heterocyclic aromatic amines: the results of two European projects compared

, 1998
This report describes two studies which compared the results of the analyses of four heterocyclic aromatic amines (HAAs): 2-amino-3-methylinidazo[4,5-f] quinoline (IQ); 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx); 2-amino-3,4,8-trimethylimidazo[

Methodical approach for determination of the heterocyclic aromatic amines in meat products using HPLC–MS/MS [PDF]

, 2021
Heterocyclic aromatic amines (HAA) are formed in foods of animal origin during the Maillard reaction due to the high creatine and creatinine contents. HAA have carcinogenic and mutagenic effects.
