摘要
The regioselectivity and stereoselectivity were examined of the addition reactions of O-, C-, N-and S-nucleophiles to D-allal- and D-galactal-derived N-mesylaziridines. The ratio of 1,4-regioselectivity (exclusive syn-1,4-addition) to 1,2-regioselectivity (exclusive anti-1,2-addition) was strictly and directly dependent on the ability of the nucleophile to coordinate with the nitrogen atom of the aziridine.
