摘　　要：以二(三氯甲基)碳酸酯(BTC)为起始原料,采用“一锅法”合成了9种新的磺酰脲化合物。并通过红外光谱、核磁共振氢谱、元素分析手段对化合物的结构进行了表征。以2-甲氧羰基苯磺酰胺计,总收率为91·7%,原药纯度达96·4%。Starting with bis （trichloromethyl）carbonate, nine new sulfonylurea compounds were synthesized through ＂one-pot method＂. The structures of these compounds were confirmed by IR spectrum, ＇ HNMR and elemental analysis. As an example the total yield of 2-methoxyl-carbonylbenzsulfamide reached 91.7% , the purity of this raw chemical was 96.4%.
