  • Stereoisomerism in 3-[N-(2-acetoxypropanoyl)-N-acylamino]quinazolin-4(3H )-ones, enantioselective acylating agents
    作者:Abdullah G. Al-Sehemi、Robert S. Atkinson、John Fawcett、David R. Russell
    DOI:10.1039/b005814i

    The title compounds diacylaminoquinazolinones (DAQs) are enantioselective acylation agents for amines and a detailed study of their stereostructures was undertaken with the aim of understanding how this enantioselectivity arises. The N–N bond in these DAQs is a chiral axis. Even where both N-acyl groups are (S)-2-acetoxypropanoyl, the N–N bond is still a chiral axis because in the most stable conformation of the planar imide moiety, one exo/endo orientation of the carbonyl groups is much preferred over the alternative (endo/exo) as revealed by NMR spectroscopy. A conformational preference within the 2-acetoxypropanoyl grouping accounts for the presence of a single exo/endo conformation in solution for some of these DAQs (see above) but an interconverting exo/endo⇌endo/exo mixture for others. Where a single exo/endo conformation is present in solution, evidence is presented that this closely resembles the X-ray determined crystal structure. A mechanism for the second acylation step to form these DAQs is proposed, which involves preliminary O-acylation of the 3-(monoacylamino)quinazolinone.
    标题化合物二酰喹唑啉酮(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-(单酰基)喹唑啉酮的初步O-酰化。
  • Aziridination of cyclic dienes with enantiopure 3-acetoxyaminoquinazolin-4(3H)-ones

    Aziridination of cyclopentadiene and cyclohepta-1,3-diene with (S)-3-acetoxyamino-2-(3-hydroxy-2,2-dimethylpropyl)quinazolin-4(3H)-one 6 (Q1NHOAc) in the presence of titanium(IV) tert-butoxide in dichloromethane takes place highly diastereoselectively: X-ray structure determinations show that the preferred sense of diastereoselectivity in both cases is the same as that previously found for aziridination of butadiene with 6. Aziridination of cyclohexa-1,3-diene with 6 was less diastereoselective in dichloromethane solution but highly diastereoselective in acetonitrile: in this solvent two diastereoisomeric cis-4-(Q1-amino)cyclohexen-3-ols 27 and 28 were also obtained as by-products. The same two amino alcohols were obtained by ring-opening of the aziridine with acid and were each converted into Q1-free oxazolidinones having optical rotations which were similar in magnitude but opposite in sign.
