Adaption of an easy to use, automated, capsule-based synthesis approach for the rapid preparation PROTAC-like molecules.

The synthesis and analytical applications of the new heterocyclic ligand are described. The complexation reaction of the ligand with some cations was studied in aqueous methanol at room temperature using the spectrophotometric method. Results revealed that only the absorption spectra of the Fe (III)–ligand complex show a high redshift of the absorption maximum in the aqueous methanol soluti...

A droplet microfluidic-based synthesis approach allows rapid optimization and fine emission color tuning of rare-earth-doped upconversion nanoparticles.

(Diacetoxyiodo)benzene has been used as an efficient catalyst for an improved and rapid one-pot synthesis of biscoumarin derivatives in excellent yield under reflux condition using water as a environmentally benign reaction medium. This aqua mediated Knoevenagel condensation of various aromatic and hetero-aromatic aldehydes with 4-hydroxycoumarin using catalytic amount of (diacetoxyiodo)benzene...

A rapid and efficient one-pot, four-component protocol towards the synthesis of polyhydroquinoline derivatives has been developed. The condensation of aldehyde, dimedone, ethyl acetoacetate and ammonium acetate in presence of stannous chloride was carried out under solvent free condition to synthesize a variety of polyhydroquinoline derivatives in good to excellent yields. Stannous chloride was...

3-methyl-1-(4-sulfobuthyl)-1-H-imidazol-3ium hydrogen sulfate, as a dual acidic ionic liquid (DAIL), was found to be an efficient catalyst for the simple, rapid and green synthesis of substituted trisphenols from the condensation of different substituted phenols and 2,6-bis (methylol) phenols (BMP). DAIL catalyst efficiently promoted the reaction between phenols and BMPs with a variety of funct...

The possible involvement of nucleic acid and protein synthesis in light-regulated chlorophyll formation by rapidly greening leaves has been studied.Removing leaves from illumination during the phase of rapid greening results in a reduction in the rate of pigment synthesis; cessation occurs within 2 to 4 hours. Etiolated leaves which exhibit a lag in pigment synthesis when first placed in the li...
