除非有另外的限定,这里的技术术语取其惯常的含义,特别是在《麦格劳-希尔科学技术术语词典》第6版(McGraw-Hill Dictionary of Scientific and TechnicalTerms,6th edition)中限定的含义。
某些实施方式中,方法包括通过以下路径(方案1)合成取代的N-(吡啶基)芳基噁唑烷酮。
方案1
方案1中,第一中间体(4)在Rxn 1中与第二中间体(6)偶联反应生成偶联产物(7),所述偶联产物而后在Rxn 2中与缩水甘油酯反应生成化合物(1)。
方案2
方案2中,中间体6可以通过下述方法生成,中间体5a与2当量的强碱比如C1-C6烷基锂例如正丁基锂或叔丁基锂反应,然后加入合适的亲电体比如ZnCl2或B(OR)3即C1-C6三烷氧基硼酸酯比如硼酸三异丙酯。亲电体为三烷氧基硼酸酯时,所得反应混合物经后处理得到硼酸6a。若将5a的二价阴离子与环硼酸酯(cyclic boronate ester)反应,而后即可分离得到环硼酸酯(cyclic boronic acid ester)6b。进一步讲,如果亲电体为ZnCl2,而后可以分离得到锌反应剂6c。可选择地,硼酸可以通过Miyaura加硼途径(Miyaura borationprocedure)(Miyaura Top.Curr.Chem.2002,219,11-59)制备。该反应中,二硼酸双酯比如二硼酸的二频那酯在钯催化剂作用下偶联到卤代芳烃(5a)上,生成的硼酸酯6b可以在酸水溶液中水解成为硼酸6a。此外,三氟硼酸衍生物6d能够通过硼酸6a与KF和/或KHF2反应生成。
以上两个方案中,X为离去基团。某些实施方案中,X选自Cl、Br、I和三氟甲磺酸酯。
X1为离去基团,某些实施方案中,X1为卤素比如Cl、Br或I。
Het为任意取代的包括至少一个N、O或S原子的五或六元杂环。包括任意取代的吡咯、呋喃、哌嗪、哌啶、咪唑、1,2,4-三唑、1,2,3-三唑、四唑、吡唑、吡咯烷、噁唑、异噁唑、噁二唑、吡啶、嘧啶、噻唑或吡嗪。在某些方面,Het为任意取代的四唑或2-甲基-四唑-5-基。某些实施方式中,Het无取代基或者有1或2个取代基。
R1a和R1b独立地选自H和F,至少一个为F;
Y选自ZnCl、BF3和BR3R4,其中R3和R4独立地选自OH和任意取代的C1-C6一元和二元醇,其中R3和R4在一起可以成环。某些实施方式中,Y为B(OH)2或频那醇硼酸酯(pinacolatoborate),即
比如B(OH)2。C1-C6一元和二元醇可以被C1-C4烷基任意取代。可以通过根岸反应(Negishi reaction)生成其中Y为ZnCl的化合物(Negishi:Chem.Ind.1988,33,381-407)。
某些实施方式中,Het可以是非取代的或被一个或多个取代基任意取代的,例如,独立地选自由卤素、羟基、氨基、C1-4烷氨基、二(C1-4烷基)氨基、氰基、硝基、C1-4烷基、C1-4烷氧基、C1-4酰基、C1-4硫代烷基、C1-4硫氧烷基(thiooxoalkyl),卤素取代的C1-4烷基和卤素取代的烷氧基组成的组。
还是在方案1中,R2为任意取代的苯基或任意取代的C1-C6烷基。某些实施方式中,苯基和C1-C6烷基是非取代的或独立地被卤素或烷氧基比如C1-4烷氧基任意取代。在某些实施方式中,R2为苄基,和R为H。
交叉偶联反应Rxn 1中适合的催化剂为钯配合物,例如膦钯配合物双三苯基磷二氯化钯(Ⅱ),四(三苯基膦)钯(0),以及在PCy3存在下从Pd2(dba)3(dba=苯亚甲基丙酮)原位反应制备的化合物。钯配合物与偶联的底物的比例不是决定性的,但发现大约为1摩尔%(相对于4或6)是有用的。
环化反应生成噁唑烷酮环在Rxn 2中实现,通过在1,3-二甲基-3,4,5,6-四氢-2(1H)-嘧啶酮(DMPU)存在下将7与强碱反应,所述强碱比如六甲基二硅化锂或有机锂盐比如正丁基锂,然后与缩水甘油酯比如R-(-)-缩水甘油酯,例如丁酸酯,反应得到化合物1(R=H)。一个实施方式以六甲基二硅化锂为碱,THF为溶剂,在DMPU存在下进行反应,温度在大约0℃-大约30℃之间,7与甘油酯的化学配比为摩尔数大约1:1。
如果需要,化合物1(R=H)可进一步转化为二氢磷酸盐,例如,通过按照众所周知的方法与POCl3反应,例如,化合物1(R=H)可以与POCl3反应,而后进行水淬灭(quench)或进行使用三氯氧磷的保护形式比如POCl(OBn)2的两步反应,第一步制备磷酸三酯,第二步移去保护基团(例如H2/Pd-C移去苄基酯)。可选择地,5-羟甲基-噁唑烷酮可以与P(N-iPr2)(O-tBu)2反应,随后与氧化剂如mCPBA进行氧化反应,而后与碱或酸水溶液反应去掉叔丁酯。
生成的二氢磷酸盐化合物1(R=PO(OH)2)可以通过与NaOMe或其他合适的含钠碱反应进一步转变为药学上可接受的盐比如化合物1的二钠盐(R=PO(O)22Na)。
药物化学领域的技术人员会理解,术语“药学上可接受的盐”是指与合适的生物相容的阳离子和/或阴离子生成的盐。所述阳离子包括金属元素阳离子,比如钠、锂、钾、镁、铝、钙、锌和有机含氮碱的季铵阳离子,比如N,N’-二苄基乙二胺、氯普鲁卡因、胆碱、二乙醇胺、乙二胺、N-甲基葡萄糖胺和普鲁卡因的盐。所述阴离子包括无机酸的阴离子,所述无机酸比如盐酸、氢溴酸、硫酸、磷酸、硝酸、高氯酸、延胡索酸、醋酸、丙酸、丁二酸、乙醇酸、甲酸、乳酸、马来酸、酒石酸、柠檬酸、棕榈酸、丙二酸、羟基丙二酸、苯乙酸、谷氨酸、苯甲酸、水杨酸、延胡索酸、甲苯磺酸、甲基磺酸、萘-2-磺酸、苯磺酸、羟基萘甲酸、氢碘酸、苹果酸、甾酸(steroic)、鞣酸及类似酸。
用本方法制备的噁唑烷酮不同于按照US 20070155798方法制备的噁唑烷酮。按照此处描述的方法制备的噁唑烷酮由于未用含锡的反应物所以不含有锡杂质。另外,有些实施方式中,发现有二聚物杂质,例如,在含有使用三氯氧磷(POCl3)将羟基转化为二氢磷酸盐的反应的批次(batch)中。具体地,一分子TR-701分子与含有至少一个P-Cl键的磷酸
酯分子形成二聚物,比如具有以下结构的二聚物
杂质以可检测的量存在,低于组合物重量的约10%,在有些情况中少于9%、8%、7%、6%、5%、4%、3%、2%或1%,比如低于0.1%或0.05%。因此,在有些实施方式中,组合物含有根据本过程制备的噁唑烷酮和二聚物。在有些实施方式中组合物含有不含任何锡杂质的噁唑烷酮。
本方法制备的噁唑烷酮用于药物,特别是如US20070155798(已通过引用包括在本申请内)详细公开的用于阻碍细菌的生长。
