摘要 为控制罗库溴铵产品中的有关物质,分别合成了欧洲药典5.4版所载罗库溴铵的5种有关物质——2β-(4-吗啉基)-16β-(1-吡咯烷基)-5α-雄甾烷-3α,17β-二醇(1)、2β-(4-吗啉基)-16β-(1-吡咯烷基)-5α-雄甾烷-3α,17β-二醇-17-乙酸酯(2)、1-[3α,17β-二羟基-2β-(4-吗啉基)-5α-雄甾烷-16β-基]-1-(2-丙烯基)吡咯烷鎓溴化物(3)、1-[3α,17β-双(乙酰氧基)-2β-(4-吗啉基)-5α-雄甾烷-16β-基]-1-(2-内烯基)吡咯烷鎓溴化物(4)和1-[3α,17β-双(乙酰氧基)-2β-(1-吡咯烷基)-5α-雄甾烷-16β-基]-1-(2-内烯基)吡咯烷鎓溴化物(5),并经~1H NMR、^(13)C NMR和MS等确证结构。 To perform the quality control of rocuronium bromide, five related substances recorded in EP 5.4 were prepared. They are 2β- (4-morpholinyl) - 16β- (1-pyrrolidinyl) -5α-androstan-3α, 17β-diol (1), 3ct-hydroxy-2β- (4- morpholinyl) -16β- (1-pyrrolidinyl)-5ot-androstan-17β-yl acetate (2), 1-[3α,17β-dihydroxy-2β- (4-morpholinyl)-5α- androstan- 16β-yl] - 1- (2-propenyl) pyrrolidinium (3), 1- [3 et, 17β-bis (acetyloxy) -2β- (4-morpholinyl) -5~t-androstan- 16β- yl]-l-(2-propenyl) pyrrolidinium(4) and 1-E3a,17β-bis(acetyloxy)-2β-(1-pyrrolidinyl)-5α-androstan-16β-yl]-l-(2- propenyl) pyrrolidinium (5). Their structures were confirmed by 1H NMR, βC NMR and MS.
