This work demonstrates the optimization of an efficient, mild, and environmentally friendly
synthetic approach to access a diverse library of N-naphthoyl thioureas. These derivatives …

BACKGROUND Deep eutectic solvents (DESs) are prepared by mixing solid organic
precursors to form a liquid driven from strong hydrogen‐bond interactions. The physical and …

Nano titania-supported sulfonic acid (n-TSA) has found to be a highly efficient, eco-friendly
and recyclable heterogeneous nanocatalyst for the solvent-free synthesis of 2, 4, 6 …

Described is a visible light-promoted three-component tandem annulation of amines,
aryl/alkyl isothiocyanates, and α-bromoesters to form 2-iminothiazolidin-4-ones in the …

We have developed a photocatalyst/base/metal-free, visible-light-driven three-component
annulation protocol to access fully substituted 2-iminothiazolidin-4-one derivatives from …

A convenient and efficient methodology for the synthesis of densely substituted pyrrole-
fused isocoumarins, which employs solid-supported silica sulfuric acid (SSA) as catalyst …

Abstract Nano photo-catalyst 'TiO 2-P25-SO 3 H'has been synthesized for the first time as a
covalently grafted solid acid and used for the oxidation of different aromatic alcohols to the …

A highly efficient one-pot synthesis of thiazolidin-4-ones via [3+ 2] cycloaddition of aza-
oxyallylic cations with isothiocyanates is developed. The aza-oxyallyic cations were …

In this paper, an efficient synthesis of 2-iminothiazolidin-4-ones through a copper-catalyzed
tandem annulation reaction of alkyl amines, isothiocyanates and diazo acetates is …

A novel and efficient protocol for the Cs 2 CO 3-catalyzed [3+ 2] annulation of β-oxo-
acrylamides with acyl isothiocyanates has been developed under mild reaction conditions …
