由α-二酮和尿素在酸或碱的催化下制得一系列取代甘脲(W_1和W_2),并对W_1和W_2进行的~1H NMR、~(13)CNMR、和MS分析表明我们合成得到了目标产物。
A series of substituted glycolurils (W_1 and W_2) were prepared from α-diketones and urea catalyzed by acids or bases. The ~ 1H NMR, ~ (13) CNMR and MS analyzes of W_1 and W_2 showed that we synthesized Get the target product.
