• Aziridination of β-substituted styrene derivatives with 3-acetoxyaminoquinazolin-4(3H)-ones: probing transition state geometry from changes in diastereoselectivity

  Reaction of (S)-3-acetoxyamino-2-[1-(t-butyldimethylsilyloxy)ethyl]quinazolin-4(3H)-one 5 (Q1NHOAc) with styrene and R(β)-substituted E-styrenes (R = SiMe3, Me, CH2Cl, CHCl2) gives the corresponding aziridines diastereoselectively. The diastereoselectivity increases in the same sense from 5 ∶ 1 → 20 ∶ 1 as the electron-withdrawing character of R increases [H(Me), CH2Cl, CHCl2] but is accompanied by a decrease in yield of aziridine. A similar increase in diastereoselectivity is found in the reaction of 3-acetoxyamino-2-(2,3,3-trimethylpropyl)quinazolin-4(3H)-one 38 (Q4NHOAc) with the same β-substituted styrenes.An explanation for these observations is offered based on a tighter, more symmetrical transition state for the aziridination of styrenes bearing the more electron-withdrawing β-substituents and is supported by SCF calculations.

  (S)-3-乙酰氧胺基-2-[1-(叔丁基二甲基硅氧基)乙基]喹唑啉-4(3H)-酮5 (Q1NHOAc)与苯乙烯及R(β)-取代的E-苯乙烯(R = SiMe3, Me, CH2Cl, CHCl2)的反应，可选择性地生成相应的氮丙啶。随着R的吸电子特性增强[H(Me), , ]，立体选择性从5:1增加到20:1，但氮丙啶的产率却降低。3-乙酰氧胺基-2-(2,3,3-三甲基丙基)喹唑啉-4(3H)-酮38 (Q4NHOAc)与相同的β-取代苯乙烯反应，也观察到类似的立体选择性增加。这些现象的解释基于更紧密、更对称的过渡态，用于带有更强吸电子β-取代基的苯乙烯的氮丙啶化，并通过SCF计算得到支持。

  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.

• Carbon–hydrogen bond insertion reactions of 3-acetoxy-aminoquinazolin-4(3H)-ones with cyclic dienes: stereochemistry and mechanism

  cyclohexadienyl ring carbon has been correlated with that at the 6-position of the major aziridine diastereoisomer co-produced in the reaction. A mechanism involving concerted insertion into the C–H bond of the diene by QNHOAc is proposed with endo-overlap of both double bonds of the diene with the Q group in the transition state.
