Starting from 4-androstenedione, three novel 3-oxo-4-aza-5-androstene-17-oxime derivatives 7, 8 and 9 were synthesized through oxidation ring cleavage, amination ring closure, oximation,and substitution.
以4雄烯二酮为起始原料,经过氧化开环、氨解闭环、肟化、取代等4-步反应,合成了3个新的3-羰基-4-氮杂-5-雄甾烯-17肟衍生物7、8和9,并用质谱、1HNMR、13CNMR等测试手段对目标化合物的结构进行了表征。
One of key factors,which hindered producing androst-4-ene-3,17-dione(AD)on industrial scale is that the yield of androst-4-ene-3,17-dione is low.
生物转化法生产雄烯二酮还未实现大规模工业化生产的主要原因之一是雄烯二酮转化率低。
Four analytical methods including TLC,UV,HPLC and GC were compared on the detecting of the transformation of phytosterol to androst-4-ene-3,17-dione in fermentation samples.
利用植物甾醇和雄烯二酮的标品以及发酵液作为待测样品,比较了薄层色谱法,紫外可见光分光光度法,高效液相色谱法和气相色谱法4种分析方法,得出分析效果最好的方法是气相色谱法;结合生产的实际情况,建立了微生物转化植物甾醇为雄烯二酮的检测方法,先用TLC薄层层析法分析,后有选择性的进行气相色谱分析。
