Regiospecific reductive ringcleavage 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 new synthetic protocol for the LiAlH4-promoted reduction of non-activated aziridines under microwave conditions was developed. Thus, ring opening of 2-(acetoxymethyl)aziridines provided the corresponding β-amino alcohols, which were then used as eligible substrates in the synthesis of 5-methylmorpholin-2-ones via condensation with glyoxal in THF. The same procedure was applied for the preparation
