A common heterocyclic compound, the chiral-catalyst compound, name is 1,4,7,10,13-Pentaoxacyclopentadecane,cas is 33100-27-5, mainly used in chemical industry, its synthesis route is as follows.,33100-27-5
To the sodium salt of 2-nitroimidazole prepared above was added acetonitrile (50 ml), 15-crown-5-ether (3.5 ml, 14.3 mmol) and 4-bromo-2-methyl-2-butene (2 ml; 17.4 mmol). The mixture was stirred at RT for ca 16 h. and then the solvent was removed to leave a crude semi-solid which was purified by column chromatography on silica. The intermediate product, 1-(3-methyl-2-butenyl)-2-nitroimidazole (80percent yield) was eluted using a mixture of petroleum ether (40-60)/ethyl acetate (ratio 4:1 respectively).
As the rapid development of chemical substances, we look forward to future research findings about 33100-27-5
