• Kinetic resolution of amines with enantiopure 3-N,N-diacylaminoquinazolin-4(3H)-ones

  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。

  Amines are efficiently acylated by both cyclic and acyclic anhydrides by dissolving them in an aqueous medium with the help of a surfactant, sodium dodecyl sulfate (SDS). Cyclic and acyclic anhydrides react with equal ease with an amine, and amines with various stereo-electronic factors react at the same rates with an anhydride.

  The first B(C6F5)3‐catalyzed deoxygenative reduction of amides into the corresponding amines with readily accessible and stable ammonia borane (AB) as a reducing agent under mild reaction conditions is reported. This metal‐free protocol provides facile access to a wide range of structurally diverse amine products in good to excellent yields, and various functional groups including those that are reduction‐sensitive
