摘要

A study of the cycloaddition behavior of a series of diazoazoles with electron-rich dipolarophilea has been carried out. 3-Diazo-4-methyl-5-phenylpyrazole readily reacta with ynamines, enamines, and vinyl ethers to give 1, 7-cycloadducts. The trisubstituted olefinic dipolarophiles, l-(diethylamino)-2-methyl-l-propene and l-ethoxy-2-methyl-l-propene, were also found to react regiospecifically with the above diazopyrazole to give the anticipated ...
