An easy and efficient method for the synthesis of novel deoxycholic acid bis-1,3,4-thiadiazol-carbamate derivatives under microwave irradiation has been developed. Twelve new methyl 3α,12α-bis-[(5-aryl-1,3,4-thiadiazol-2-yl) carbamoyloxy]-cholan-24-oates were obtained in better yield (78–91%) and shorter time (15–22 min). Their structures were identified by 1H NMR, IR, MS spectra and elemental analyses
已经开发了一种在微波辐射下合成新型脱氧胆酸双-1,3,4-噻二唑-氨基甲酸酯衍生物的简单有效的方法。以更高的产率 (78–91%) 和更短的时间获得了 12 种新的 3α,12α-双-[(5-芳基-1,3,4-噻二唑-2-基) 氨基甲酰氧基]-cholan-24-oates 甲酯 ( 15–22 分钟)。它们的结构通过 1H NMR、IR、MS 光谱和元素分析进行鉴定。
