Enhanced toxicity of the protein cross-linkers divinyl sulfone and diethyl acetylenedicarboxylate in comparison to related monofunctional electrophiles.

Chem. Res. Toxicol. 24(9) , 1457-9, (2011)

Previously, we determined that diethyl acetylenedicarboxylate (DAD), a protein cross-linker, was significantly more toxic than analogous monofunctional electrophiles. We hypothesized that other protei...

3,4,5-Trisubstituted Furan-2(5H)-one Derivatives: Efficient one-pot Synthesis and Evaluation of Cytotoxic Activity.

Drug Res. (Stuttg.) , (2014)

A series of 3,4,5-trisubstituted 2(5H)-furanone derivatives was synthesized through one-pot reaction of amines, aldehydes and diethyl acetylenedicarboxylate. Silica sulfuric acid efficiently catalyzes...

Diels-Alder reactivity of polycyclic aromatic hydrocarbon bay regions: implications for metal-free growth of single-chirality carbon nanotubes.

J. Am. Chem. Soc. 131(44) , 16006-7, (2009)

A soluble bisanthene derivative, 4,11-dimesitylbisanthene, has been synthesized in three steps from bianthrone. In hot toluene, this bisanthene undergoes a clean Diels-Alder reaction with diethyl acet...
