Herein, we report that potassium tert-butoxide-catalyzed intramolecular anionic cyclization of (2-alkynylbenzyl)oxy nitriles has been developed for the preparation of substituted benzofuroazepines. The effects of solvent, base, temperature, reaction time, and amount of base on the efficiency of cyclization reaction was investigated. The results led us to(More)
Selenium is an essential trace element for human health and has received attention for its role as a nutrient. The combination of exercise and nutrients has been proposed to promote health. The aim of this study was to determine the effects of a diet supplemented with diphenyl diselenide (PhSe)2 and swimming exercise on memory of middle-aged rats. Male(More)
Results on the synthesis of tetrahydroselenophene derivatives from 1-butylseleno-4-alkynes by electrophilic cyclization using iodine as the electrophilic source are presented. This methodology was carried out via a simple process under mild reaction conditions providing the cyclized products in high yields. Electrophilic sources, such as PhSeBr, CuCl(2),(More)
