Conclusions
-
1.
We have developed a synthesis of derivatives of N-alkoxyaziridine-2-carboxylic acids by reaction of alkoxyamines with the corresponding vicinal dibromides in acetonitrile in the presence of triethylamine.
-
2.
We have demonstrated the high configurational stability (ΔG ≠inv =30–32 kcal/mole) and thermal stability of derivatives of 1-alkoxyaziridine-2-carboxylic acids.
-
3.
We have separated by crystallization the geometric isomers (cis and trans invertomers) of 1-methoxyaziridine-2-carboxamide.
-
4.
We have synthesized the first optically active 1-alkoxyaziridines with two or more asymmetric centers in the molecule. We have prepared pure diastereomers of N-[(S)-α-phenylethyl]- trans-1-methoxyaziridine-2-carboxamide.
-
5.
We have observed the stereospecific trans animation of 1-alkoxyaziridine-2-carboxylic esters by sterically hindered amines.
