B-rac与(R)-四氢呋喃-2-羧酸(11b)缩合生成非对

映异构体12b和13b,经选择性结晶得到(R,R)-非对映异构

[10]

体B。该路线以6为起始物料制备中间体B,共8步,总收

率29%。该路线在吗啉酮片段的构建中使用到-78℃的低温

条件,且正丁基锂和二异丁基氢化铝对水和空气敏感,工业化

难度较大。

3 中间体C的合成路线

Boc-L-丝氨酸(2c)与2-溴-1,1-二甲氧基乙烷反应

得到3c,再用甲磺酸脱保护得到片段4c;6与碘甲烷发生酯化

反应得到5c,用三氟乙酸脱苄后与正己基碘反应得到6c;然后

[11]

与Boc-肼反应得到7c,在碱性条件下水解得到片段8c。

片段4c和片段8c在EDC介导下偶联,得到酰胺10c,用甲

1c,在碱性条件下水解得到羧酸12c,三步收率磺酸处理,得到1

3%。也可以用氨基酸9c与片段8c缩合,再经环合直接得为6

到中间体12c,避免了羧基的酯化和水解,但两步收率仅

[11]

为16%。

11]

文献报道了两种中间体12c脱羧制备中间体C的方法

中间体12c用4,4‘-二氯二苯二硫醚和9-均三甲苯基-2,7

-二甲基-10-甲基吖啶盐处理后,加入2,6-二甲基吡啶,在

室温下用蓝色发光二极管照射下脱羧,经快速色谱法纯化,得

到中间体C,收率92%,该方法采用常规反应设备难以放大规

模,若采用连续流反应可以持续化生产。另一种为两步法,通

羟基邻苯二甲酰亚胺酯中间体13c实现,总收率为过制备N-

38%,该方法过程繁琐且收率较低,规模放大难度较大。

文献报道了用中间体B制备中间体C的方法

。苄基保

然后与甲苯磺酸护的中间体B用正己醇镁盐与1-己醇反应,

成盐,得到己基保护的中间体C,收率87%。

2.2 路线二

N-羟乙基邻苯二甲酰亚胺(16b)与2-溴-1,1-二甲氧

基乙烷反应制备17b,再脱保护得到18b;6与硫酸二甲酯反应

4b,然后与Boc-肼反应得15b;片段18b与15b在DBU得到1

催化下发生酰胺化反应得到19b,然后用甲磺酸处理19b得到

[5]

B-rac。按照路线一的方法进行拆分,得到中间体B。该路

总收率19%,该路线采用拆分的方线以6为起始物料共7步,

法制备中间体B,收率较低。文献报道了从母液中回收中间体

4 巴洛沙韦酯(1)的合成

4.1 按中间体A+B的方式合成

山 东 化 工

SHANDONGCHEMICALINDUSTRY            2020年第49卷

4.2 按中间体A+C的方式合成

中间体A和C在1-丙基膦酸酐和甲磺酸作用下缩合,经

结晶得到甲磺酸盐5,收率85%,然后5用氯化锂脱去正己基保

护,得到巴洛沙韦(2),收率91%,然后与氯甲基碳酸甲酯反应

[11]

得到巴洛沙韦酯(1),收率93%。该合成路线使用正己基保

护的片段C,其制备过程避免了低收率的拆分工艺,片段C与外

收率较高。消旋片段A偶联的非对映选择性较好,

中间体A和B在1-丙基膦酸酐和甲磺酸作用下缩合,随

后用溴化苄和碳酸钾处理,得到苄基保护的中间体4,收率

53%;中间体4用氯化锂脱苄得到巴洛沙韦(2),收率94%,然

[10]

后与3反应得到巴洛沙韦酯(1),收率93%。该合成路线需

要用低收率的拆分方法制备片段B,片段B和外消旋片段A偶

联时非对映选择性较差,且收率较低。
