Synthesis of novel pyridazino[1,6-a]indole-2,4(1H,3H)-dione and pyridazino[1,6-a]indol-2(1H)-one via intramolecular electrophilic aromatic substitution

Results in Chemistry, 2022
Cyclization of judiciously substituted N-aminoindole species provides a convenient synthetic route to ABE building block types I and II as tricyclic skeleton commonly found in the motif of indolic alkaloids. The approach consists in obtaining a tricyclic

What is the best treatment for diabetic neuropathy? [PDF]

, 2004
Tricyclic antidepressants, anticonvulsants, and capsaicin reduce the pain of diabetic neuropathy; limited data suggests that lidocaine patches may also be efficacious.

Characterization of the Cubamyces Menziesii Terpenome

ChemBioChem, EarlyView.
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Rearrangement of o-Nitrobenzaldehyde in the Hantzsch Reaction

Molecules, 2001
The reaction of 5-hydroxy-2-nitrobenzaldehyde with ethyl acetoacetate in ammonia gave the two expected isomeric 1,4- and 1,2-dihydropyridines resulting from the normal Hantzsch reaction.

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

ChemCatChem, EarlyView.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

Rapid estimation of concentration of aromatic classes in middistillate fuels by high-performance liquid chromatography [PDF]

An high performance liquid chromatography (HPLC) method to estimate four aromatic classes in middistillate fuels is presented. Average refractive indices are used in a correlation to obtain the concentrations of each of the aromatic classes from HPLC ...
