Then the product compound reacted with NH 3 and hydrogenated with Pd/C to get 3-oxo-4-aza-5α-androsta-17β-carboxylic acid, which was esterified with anhydrous CH 3OH, dehydrogenated with DDQ/BSTFA, and reacted with t-butylamino magnesium bromide to get finasteride.
方法 以孕烯醇酮为原料制得 3 羰基 4 雄甾烯 17β 羰酸 ,用高锰酸钾和高碘酸钠打开A环 ,然后与氨反应闭环 ,再经Pd/C催化氢化制得 4 氮杂 5α甾体化合物 ,然后 17β 羰酸成酯 ,DDQ脱去 1,2 氢 ,最后与叔丁胺的格氏试剂反应制得非那雄胺。
In order to reduce the cost more and accelerate the application in the civil area, the laser rapid forming technology with low cost hydrogenation dehydrogenization ( HDH ) titanium alloy powders had been investigated, and the following results were obtained:1 Disclosed the formation mechanisms and influencing factors of t.
为进一步降低该技术的成本,促进其在民用领域的发展,本文针对低成本氢化脱氢(hydrogenmiondehydrogenization,HDH)钛合金粉末的激光快速成形进行研究,取得的主要成果如下: 1。
Asymmetric hydrogenation of ketone is one of the most important and widely used synthetic methods to produce chiral alcohols in both organic synthesis and chemical industry In 1990s,Noyori and co-workers developedη~6-arene Ru(Ⅱ) complex withβ-diamines ligand which is efficient in transfer hydrogenation of ketones instead of H_2-hydrogenation of ketones in neutral and basic conditions.
该催化剂在碱性条件下主要发生转移氢化反应,很难发生氢气氢化反应。
