【正文】 出液澄清為止，加入環(huán)已酮，再蒸餾 除水 到流出液澄清。環(huán)已酮羰基上的氧原子的未共享電子對進入鋁原子的空軌道，而羰基碳原子則作為陰氫的受體，接受甾體 C－ 3上陰氫離子進攻；整個反應在空間上形成一個六元環(huán)的過渡態(tài)。 在精制用的乙醇母液中，含有少量的乙酰皂素和雙烯醇酮醋酸酯，可用 皂化－萃取法 回收套用。 10 OOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3OBrO HC OOC H3OO HC OOC H2IOO HC OOC H2O A cOO HH2N C N H NC H2O A cOO HN N H C N H2OOH2N C N H NC H2O A cO HN N H C N H2OHOO犁頭霉菌 黑根霉菌 工藝路線 11 OOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3OBrO HC OOC H3OO HC OOC H2IOO HC OOC H2O A cOO HH2N C N H NC H2O A cOO HN N H C N H2OOH2N C N H NC H2O A cO HN N H C N H2OHOOOOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3OBrO HC OOC H3OO HC OOC H2IO O HC OOC H2O A cO O HH2N C N H NC H2O A cO O HN N H C N H2OOH2N C N H NC H2O A cO HN N H C N H2OHOO黑根霉菌氧化 溴代 脫溴 碘化 置換 梨頭霉菌氧化 醋酸化 合物 S 12 ? 一、合成路線 ? （一）經醋酸可的松的合成路線 OOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3OBrO HC OOC H3OO HC OOC H2IOO HC OOC H2O A cOO HH2N C N H NC H2O A cOO HN N H C N H2OOH2N C N H NC H2O A cO HN N H C N H2OHOOOOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3OBrO HC OOC H3O O HC OOC H2IO O HC OOC H2O A cO O HH2N C N H NC H2O A cO O HN N H C N H2OOH2N C N H NC H2O A cO HN N H C N H2OHOOOOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3OBrO HC OOC H3OO HC OOC H2IOO HC OOC H2O A cOO HH2N C N H NC H2O A cOO HN N H C N H2OOH2N C N H NC H2O A cO HN N H C N H2OHOO13 OOOHC OC H2O HO HOHOC OA c OC H3C OOHC H3OC OOC H3OC OOC H3O HBrC OOC H3O HC OOC H2IO HC OOC H2O A cO HC OOC H3OOHC OOC H3OOC OOC H3
