  Regiospecific reductive ring cleavage was accomplished in the reaction of N-α-methylbenzyl substituted aziridine-2-carboxylate and aziridine-2-methanol under a catalytic hydrogenation condition. The regiospecificity was determined by the substituent at C-2.

  N -α-甲基苄基取代的氮丙啶-2-羧酸酯和氮丙啶-2-甲醇在催化氢化条件下的反应完成了区域特异性还原环的裂解。区域特异性由C-2上的取代基确定。

  A Pd‐catalyzed enantiospecific and regioselective ring‐opening Suzuki–Miyaura arylation of aziridine‐2‐carboxylates was developed. The cross‐coupling allows for the asymmetric preparation of enantioenriched β2‐aryl amino acids, starting from commercially available enantiopure d‐ and l‐serine esters. The mechanism and selectivity of the reaction was rationalized based on computational models.

  homochiral alpha-amino acids have been prepared in good yield via regioselective reaction of higher order cuprates with (2S)-N-para-toluenesulfonylaziridine-2-carboxylic acid 4. The reaction was much less regioselective and low yielding when higher order cuprates were reacted with the more hindered aziridine carboxylic acid 30, the principal products being protected beta-amino acids. Reaction of lithium tr

  通过高阶铜酸盐与（2S）-N-对甲苯磺酰基氮丙啶-2-羧酸4的区域选择性反应，已经以高收率制备了多种同手性α-氨基酸。当较高阶时，该反应的区域选择性低得多，并且收率低。铜酸盐与受阻更强的氮丙啶羧酸30反应，主要产物是受保护的β-氨基酸。然而，三甲基甲硅烷基乙炔基锂与氮丙啶酸30的反应产生了被保护的α-氨基酸，该α-氨基酸被转化为被保护的异亮氨酸酯37。

  Excellent regiospecificity has been achieved in the reaction of carbon nucleophiles with N-para-toluenesulfonylaziridine-2-carboxylic acid (6, R = H protected as the anion. This has been developed into a general and high yielding synthesis of optically pure α-amino acids containing one chiral centre. When the aziridine (20) containing a second chiral centre was used, only lithium trimethylsilylacetylide

  The synthesis of cyclopropane derivatives via a MIRC reaction of azidirinyl-methylene-malonates is described. In this way it is possible to introduce a hydrogen, a phenylthio, a tributylstannyl and an olefinic function at the cyclopropane ring, that further contains an alkylamino substituent. Addition of CuCN catalyzed Grignard reagents gave the most promising results. The diastereoselectivity was
