Journal ArticleDOI
New hetero-annelation reactions using N-[ bis -(methylthio)-methylene]-amino and related reagents
TL;DR: In this paper, the reaction of acyclic and cyclic reagents with Gewald-type thiophene derivatives (2,3) led to annelation of pyrimidine moieties.
Journal ArticleDOI
A study of the tautomerism of 2- and 4-ethoxycarbonylthiolan-3-ones implicating stereochemical effects of ring-substitution
TL;DR: A series of 2- and 4-ethoxycarbonylthiolan-3-ones have been synthesized and studied by 1 H NMR and IR spectroscopy.
Journal ArticleDOI
Synthesis of precipitating chromogenic/fluorogenic β-glucosidase/β-galactosidase substrates by a new method and their application in the visual detection of foodborne pathogenic bacteria.

TL;DR: This method was used to synthesise novel precipitating fluorogenic substrates for β-glucosidase based on 2-(benzothiazol-2'-yl)-phenols and the application of these substrates in the detection of foodborne pathogenic bacteria was assessed.
Reference EntryDOI
The Krapcho Dealkoxycarbonylation Reaction of Esters with α‐Electron‐Withdrawing Substituents
TL;DR: The Krapcho reaction involves esters with α-electron-withdrawing substituents such as malonates, β-keto esters, and α-cyano esters as discussed by the authors.
Journal ArticleDOI
Synthesis of new fused heterocycles by annelation of thiopyrano[4′,3′:4,5]thieno[2,3- c ]pyrimidines
TL;DR: In this paper, 1.5,6,8-tetrahydro-2H-thiopyrano was used as key intermediates for annelations of thiazolo and 1,3-thiazino moieties to yield the tetracyclic target structures.
