Polyoxometalate-Driven Ease Conversion of Valuable Furfural to trans- N, N-4,5-Diaminocyclopenten-2-ones
We investigated the catalytic efficacy of silicotungstic acid (H4SiW12O40) polyoxometalate (POM) toward the reaction between furfural and amines that selectively yields trans-N,N-4,5-substituted-diaminocyclopenten-2-ones (trans-DACPs). H4SiW12O40 facilita

THERAPEUTIC CURE-PRO COMPOUNDS FOR TARGETED DEGRADATION OF BET DOMAIN PROTEINS, AND METHODS OF MAKING AND USING THEM
The present application is directed to a therapeutically useful compound, comprised of two monomers that are linked to each other through two or more reversible covalent bonds. Each monomer is a polyfunctionalized molecule comprising a bioorthogonal linker element and ligand or pharmacophore, wherein the linker and ligand/pharmacophore are covalently coupled to each other either directly or through an optional connector moiety.

Chemical cascades in water for the synthesis of functionalized aromatics from furfurals
One-pot synthetic routes from furfurals to polysubstituted aromatic compounds have been developed in water, without the need for any organic solvents. The reaction proceeds via an uncatalysed, one-pot reaction cascade through formation of a hydrazone derivative, in situ cycloaddition with a dienophile, then aromatisation. A range of substituted phthalimides can be accessed with complete control over the substitution pattern. The reaction was also extended to other dienophiles and the diene 2-furylacrolein. The phthalimide products were further elaborated to produce a variety of polysubstituted benzenes including pharmaceutically relevant compounds.

Synthesis of o -(dimethylamino)aryl ketones, acridones, acridinium salts, and 1 H -indazoles by the reaction of hydrazones and arynes
A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in good to excellent yields.

Synthesis of o -(dimethylamino)aryl ketones and acridones by the reaction of 1,1-dialkylhydrazones and arynes
A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones and acridones has been developed starting from readily available 1,1-dimethylhydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds under mild conditions, tolerates a wide range of functional groups, and provides the final products in good to excellent yields.

From aldehydes to nitriles, a general and high yielding transformation using HOF·CH3CN complex
N,N-Dimethylhydrazones of aldehydes undergo a rapid oxidative cleavage to form nitriles in very high yields on reaction with HOF·CH3CN under mild conditions. The reaction is chemoselective and proceeds rapidly without racemization. The nitriles were resistant to further oxidation, even when a large excess of the reagent was employed.

A novel, one-pot synthesis of α-C-cyanohydrazines in the presence of lithium perchlorate/diethylether solution (5.0 M)
Condensation of N,N-dimethylhydrazine, an aldehyde in lithium perchlorate/diethylether solution (5.0 M) gave N,N-dimethylhydrazone, which were treated with trimethylsilylcyanide to afford α-C-cyanohydrazine. These compounds are important precursors of nitrogen-substituted reagents.
