    摘要:
    标题化合物二酰氨基喹唑啉酮(DAQs)是针对胺的选择性酰化试剂,针对其立体结构进行了详细研究,以期理解这种对映选择性的来源。这些DAQs中的N-N键是一个手性轴。即使两个N-酰基团都是(S)-2-乙酸基丙酰基,N-N键仍然是一个手性轴,因为在平面亚胺部分的最稳定构象中,一种外-内构象的羰基基团比另一种内-外构象更为优先,NMR光谱学揭示了这一点。2-乙酸基丙酰基团内的构象偏好解释了某些DAQs在溶液中存在单一外-内构象(如上所示),而其他则存在互变的外-内⇌内-外混合物。在溶液中存在单一外-内构象的情况下,提供了证据表明,这种构象与X射线确定的晶体结构非常相似。提出了一种形成这些DAQs的第二步酰化机制,该机制涉及对3-(单酰氨基)喹唑啉酮的初步O-酰化。

  • Kinetic resolution of amines with enantiopure 3-N,N-diacylaminoquinazolin-4(3H)-ones
    作者:Al-Sehemi, Abdullah G.、Atkinson, Robert S.、Fawcett, John
    DOI:10.1039/b105917n
    日期:2002.1.7
    The title compounds (DAQs) are chiral when the two N-acyl groups are different because of the absence of rotation around the N–N bond (a chiral axis). Enantiopure DAQs have been obtained by incorporation of a chiral centre in enantiopure form either into the substituent at the Q2-position or into one of the N-acyl groups, or into both, followed by separation of diastereoisomers. This separation is unnecessary in one case because conversion of the N-monoacylaminoquinazolinone (MAQ) into the DAQ is completely diastereoselective. Neither is separation of diastereoisomers necessary with 3-[N,N-di-(S)-2-acetoxypropanoylamino]-2-diphenylmethylquinazolin-4(3H)-one 37a: this DAQ 37a has its N–N bond rendered a chiral axis by the bias in its imide moiety wholly in favour of one exo/endo conformation.The high chemoselectivity exhibited by N,N-diacetyl- or N,N-dibenzoylaminoquinazolinones in reaction with the less hindered of two secondary amines (pyrrolidine in the presence of 1 eq. of piperidine) has a stereoselective counterpart: reaction of the above enantiopure DAQs enantioselectively with racemic amines leading to kinetic resolution. Using 1 eq. of DAQ and 2 eq. of amine, both the derivatised and unreacted amine enantiomers are recovered with high enantiomeric excess (ee) (better than 90% ee in some cases). Some of the higher ees are found in the recovered amides where non-chemoselective attack on both N-acyl groups of the DAQ has occurred: from the opposite configurations of the amine component in the two amides and from the low enantiopurity of the recovered unreacted amine, reaction of each of the N-acyl groups with complementary enantiomers of the amine is occurring (parallel kinetic resolution).Although higher ees are, in general, obtained using secondary amines, high ees are obtained in some cases using 1-phenylethylamine and, in particular, amino acid esters (valine and alanine).The sense of enantioselectivity in the reactions of these DAQs with amines is controlled by the configuration of the N–N axis: replacing the Q group in an N-(S)-2-acetoxypropanoyl-N-acetyl-bearing DAQ by phthalimide, thus eliminating the N–N chiral axis, drastically reduces the level of kinetic resolution.
    标题化合物(DAQs)在两个N-酰基团不同时是手性的,因为N-N键(一个手性轴)缺乏旋转。通过将手性中心以手性形式引入Q2-位点的取代基或其中一个N-酰基团,或两者中,随后分离diastereoisomers,得到了纯对映体的DAQs。在一个情况下,这种分离是不必要的,因为将N-单酰胺基喹唑啉酮(MAQ)转化为DAQ是完全立体选择性的。对于3-[N,N-di-(S)-2-乙酰氧基丙酰胺基]-2-二苯甲基喹唑啉-4(3H)-酮37a,也不需要分离diastereoisomers:这个DAQ 37a通过其亚胺部分的偏向完全倾向于一个exo/endo构象,使其N-N键成为一个手性轴。N,N-二乙酰基或N,N-二苯甲酰氨基喹唑啉酮在与两个次级胺中较少受到阻碍的胺(在存在1 eq.的哌啶的情况下使用吡咯烷)反应时表现出高度的化学选择性,这在立体选择性上有对应:上述纯对映体的DAQs与外消旋胺反应,导致动力学拆分。使用1 eq.的DAQ和2 eq.的胺,衍生化的和未反应的胺对映体都以高对映体过量(ee)回收(在一些情况下优于90% ee)。在一些回收的酰胺中发现较高的ee,其中非化学选择性地攻击DAQ的两个N-酰基团:从两个酰胺中胺组分的相反构型和回收的未反应胺的低对映纯度,每个N-酰基团与胺的互补对映体反应(并行动态拆分)。尽管通常使用次级胺得到较高的ee,但在某些情况下使用1-苯乙胺,特别是氨基酸酯(缬氨酸和丙氨酸)得到高ee。这些DAQs与胺反应的对映选择性的方向受N-N轴配置的控制:在带有N-(S)-2-乙酰氧基丙酰基-N-乙酰基的DAQ中,通过用邻苯二甲酰亚胺替换Q组,从而消除N-N手性轴,显著降低了动力学拆分的水平。

  • 3-(N,N-Diacylamino)quinazolin-4(3H)-ones as enantioselective acylating agents for amines

    The presence of an N-N chiral axis in a 3-(N-benzoyl-N-isobutanoyl)aminoquinazolin-4(3H)-one (DAQ) bearing a chiral substituent in the 2-position of the quinazolinone allows separation of two enantiopure diastereoisomers; one of these diastereoisomers reacts with racemic 2-methylpiperidine to give (R)(+)-1-benzoyl-2-methylpiperidine (95% ee) and (S)-2-methylpiperidine (91% ee) even using stoichiometric quantities of reagents (1 equiv. DAQ: 2 equiv. amine). (C) 2000 Elsevier Science Ltd. All rights reserved.
