Abstract
式(Ⅰa)或(Ⅰb)化合物,其中A和B每个独立地表示氢或一个,两个或三个亚萘基的取代基,这些取代基选自C<sub>1-6</sub>烷基,C<sub>1-6</sub>烷氧基,芳基,芳氧基,甲硅烷基和甲硅烷氧基;R<sup>1</sup>表示苯基,C<sub>1-6</sub>烷基,苯基C<sub>1-6</sub>烷基或式(a):其中R<sup>2</sup>表示C<sub>1-6</sub>烷基,苯基或苄基,R<sup>3</sup>表示H或OR<sup>4</sup>,其中R<sup>4</sup>是C<sub>1-6</sub>烷基或C<sub>1-6</sub>烷基甲硅烷基;n是0,或整数1或2;以及X<sup>-</sup>是对立离子;制备上述化合物的方法以及该化合物用于对映体选择性地环氧化前手性烯类化合物的用途。
Description
本发明涉及新的化合物及这种化合物作为氧转移反应催化剂的用途。
目前,使用手性催化剂,特别是Jacobsen等人的Salen锰铬合物(国际专利申请,公开号WO/91/14694)的烯类化合物催化不对称环氧化反应,是不对称合成中已确立的方法。这种催化体系的重要性主要是由于不对称环氧化反应本身用途的多样性,这种多样性是由于许多及各种各样的亲核试剂,该亲核试剂能够用于使环氧化物开环,并且提供伴随的不同范围的富对映体产品。该对映体纯产品在用于制造生物学上重要的化合物如杀虫剂,除草剂和药物方面有着越来越多的需求。
除了有机-过渡金属基催化剂如Jacobsen催化剂以外,纯的有机不对称催化剂是公知的。Hanquet等人(Tetrahedron Letters Vol.34,no.45,pp7271-7274)证明,氧杂吖丙啶鎓盐(oxaziridinium)(1S,2R,3R,4S)-N-甲基-1,2-氧桥-3-甲基-4-苯基-1,2,3,4-四氢异喹啉鎓四氟硼酸盐催化反式芪的不对称环氧化反应,并且催化甲基对甲苯基硫化物不对称氧化为相应的亚砜。上述氧杂吖丙啶鎓盐从催化量的亚铵盐和过硫酸氢钾制剂就地制备(Hanquet等人,C.R.Acad Sci.,Paris,1991,313,SII,pp625-628)。
和Salen锰铬合物及其它有机-过渡金属基催化剂不同,氧杂吖丙啶鎓盐催化剂不是通过自由基中间体起作用,因之它们可以广泛用于各种烯类底物,这是因为不需要在烯类(分子)中有π-稳定基(稳定初生的自由基),同时氧杂吖丙啶鎓盐催化剂的氧化反应是立体有择的,即顺式烯得到顺式环氧化物;反式烯得到反式环氧化物。虽然有这些优点,但是至今氧杂吖丙啶鎓盐催化剂还没有在工业规模上用于氧化体系。
目前故经发现,一系列新的氧杂吖丙啶鎓盐在烯类化合物的催化不对称环氧化反应中显示了更大的希望。所使用的催化反应是简单的,并且完全可以使用容易得到的廉价的试剂及对环境安全的溶剂。
因此,本发明首先提供式(Ia)或(Ib)的化合物:其中A和B各自独立地表示氢或一个,二个或三个亚萘基的取代基,这些取代基选自C1-6烷基,C1-6烷氧基,芳基,芳氧基,甲硅烷基和甲硅烷氧基;R1表示苯基,C1-6烷基,苯基C1-6烷基或下式(a)其中R2表示C1-6烷基,苯基或苄基,R3表示H或OR4,其中R4是C1-6烷基或C1-6烷基甲硅烷基,n是0或1或2的整数;和X是对立离子。
合适的A是氢。
合适的B是氢。
当R1表示C1-6烷基时,其实例是甲基和乙基。
R1的实例是苄基。
合适的R2是C1-6烷基。
合适的R3是C1-6烷基。
优选R1表示C1-6烷基。
对立离子X-的含义包括BF4 -,Cl-,Br-,I-,ClO4 -和PF6 -;
优选对立离子X-为BF4 -。
合适的芳基A是苯基。

式(VIa)或(VIb)化合物和式(VII)化合物之间的反应可以用任何合适的有机溶剂进行,通常是非质子传递溶剂如四氢呋喃,反应通常在低温或中等升温例如-78-50℃范围内进行。
