Crystals of (Z )-2-(1-methyl-1H-indol-3-ylmethylene)-1-aza-bicyclo[2.2.2]octan-3-one (I) were obtained from a condensation reaction of 1-methyl-1H-indole-3-carboxaldehyde with 1-aza-bicyclo[2.2.2]octan-3-one and subsequent crystallization of the product from methanol. The isomeric (E)-2-(1-methyl-1H-indol-3-ylmethylene)-1-aza-bicyclo[2.2.2] octan-3-one hydrochloride (II) was obtained by treatin...

Volatile aroma compounds were evaluated in USDA Top Choice and Select beef top loin steaks cut 1.3 cm (THIN) or 3.8 (THICK) cooked on a commercial flat grill at 177°C (LOW) 232°C (HIGH) surface temperature. Gas chromatography/mass spectrophotometry was used to evaluate volatile compounds. had more 2-octene less trimethyl pyrazine (P < 0.05) THIN than THICK steaks, whereas unaffected by s...

Diabetes mellitus (DM) is a metabolic disorder that affects people of all ages. Increased prevalence diabetes worldwide has led to the development synthetic drugs provide an interim solution ill effects issue. However, such drugs, although effective as antihyperglycemic agents, are accompanied by significant side effects, costly, and inaccessible majority in remote underdeveloped countries. Loc...

A metal-free synthesis of bifunctionalized indole derivatives was developed through a novel TBHP/TBAI-mediated oxidative coupling of C2,C3-unsubstituted indoles with arylsulfonyl hydrazide. Under the same conditions C3-methyl substituted indoles underwent a diazotization process, affording 2-sulfonyldiazenyl-1H-indoles. The former reaction simultaneously established C-S and C-N bonds through se...

One-pot three-component cyclo-condensation reaction of bis(indole-2,3-diones) with dimedone, 3-methyl-1H-pyrazol-5(4H)-one, or 6-aminouracil in boiling acetic acid afforded bis-spirocyclic oxindole...
