  Facile Synthesis of Optically Pure 1,2-Diaryl (and 1-Alkyl-2-aryl) Ethyl and Propylamines

  摘要：

  [GRAPHICS]A concise high-yielding route to synthetically useful 1,2-diaryl (and 1-alkyl-2-aryl) ethyl and propylamines in high enantiomeric purity is described. The key step of this route is the completely stereoselective addition of lithium (R)-ortho-(p-toluenesulfinyl)benzylic carbanions to (S)-N-p-toluenesulfinylimines, which takes place in very high or quantitative yields. N-Desulfinylation and C-desulfinylation of the resulting adducts can be achieved with no loss of optical. purity employing conventional methods (TFA and Raney-Ni, respectively).

  (R)-N-Sulfinylimine and (S)-N-sulfinylimine react with the ylide derived from (S)-dimethyl-[2-(p-toluenesulfinyl)phenyl]sulfonium salt, affording trans-2,3-disubstituted aziridines. A complete trans selectivity in low facial diastereoselectivity is observed when the configuration at the sulfur atoms of the reagents is the same. Otherwise, when their configurations are different, the reaction evolved

  （R）-N-亚磺酰亚胺和（S）-N-亚磺酰亚胺与衍生自（S）-二甲基-[2-（对甲苯亚磺酰基）苯基] ulf盐的叶立德反应，得到反式-2,3-二取代的氮丙啶。当试剂的硫原子处的构型相同时，可以观察到低的非对映选择性的完全反式选择性。否则，当它们的构型不同时，反应会随着面部总非对映选择性和顺/反式而发展。比率介于1 / 4.2和1/9之间。理论计算表明反应主要是通过平面自由碳负离子的演化而进行的。过渡态的相对稳定性预测反式/顺式比与实验结果非常吻合。

  An unprecedented behavior of ortho-sulfinylpropargyl carbanions in the presence of optically active sulfinylimines affords two different families of compounds: this peculiar chemodivergency is importantly affected by the nature of the employed base, and assisted by the configuration of the electrophile, displaying no alteration in the stereocontrol of both reactions. alpha-Allenylamines are formed exclusively, using R-sulfinyl aldimines as electrophiles, while homopropargylamines result when S-sulfinyl aldimines are employed.

  The reactions of the lithium (S)-alpha-(methylthio)-2-(p-toluenesulfinyl)benzyl carbanion with (S)-N-p-tolylsulfinyl aldimines evolve in a completely stereoselective manner providing a one-step synthesis of enantiomerically pure anti-1,2-disubstituted 1,2-amino sulfide derivatives.
