The effects of calcium and magnesium acetates on the formation of injection site and testicular tumors in male Wistar rats over 2 years following s.c. injections of cadmium chloride (CdCl2) were determined. The rats (25/group) received a single s.c. dose of CdCl2 (0.02 or 0.04 mmol/kg; 0.9% NaCl solutions). Calcium and magnesium acetates were administered as 3% dietary supplements for 2 weeks p...

A highly stereoselective desymmetrization reaction of δ,δ-diaryl-α-diazo-β-ketoesters catalyzed by chiral dirhodium carboxylates forms aromatic cycloaddition products in up to 97% ee.

A cuprous bromide-catalyzed heteroannulation reaction of [60]fullerene with ketoxime acetates has been exploited to prepare novel 1-fulleropyrrolines through the cleavage of N-O and C-H bonds and formation of C-C and C-N bonds under thermal conditions. A plausible mechanism for the formation of 1-fulleropyrrolines is proposed on the basis of the experimental results. The electrochemistry of the...

Thiazole is an important nucleus owing to its wide range of medical uses. It contains components that are anti-bacterial, anti-fungal, anti-malarial, anti-cancer, anti-allergic, anti-hypertensive, anti-inflammatory, and anti-psychotic, as well antioxidant, analgesic, antimicrobial. The thiazole scaffold has been detected in the more than eighteen FDA-accepted medicines addition countless resear...

Tetrahydro-4H-chromene-3-carbonitrile derivatives 4a-c where prepared from the reaction of 1,4-cyclohexane dione (1), malononitrile (2) and either benzaldehyde (3a), 2-chlorobenzaldehyde (3b) or 4-methoxybenzaldehyde (3c) in ethanol containing triethylamine. Compound 4b was used to prepare pyrazole, pyrimidine thiazole derivatives. Moreover, tetrahydrobenzo[d]thiazole derivative 18 (1) with ele...
