The synthesis of 2-aminophosphates is achieved by a SN2-type ringopening reaction of various N-protected or free aziridines with phosphoric acids in a regiospecific and/or enantiospecific way. A one-pot, two-step procedure is also developed enabling direct access to 2-aminophosphates from olefins without isolation of the aziridine intermediates.
通过各种N-保护的或游离的氮丙啶的S N 2型开环反应以区域特异性和/或对映体特异性的方式实现磷酸2-氨基磷酸酯的合成。还开发了一种一锅两步的方法,无需分离氮丙啶中间体即可直接从烯烃获得2-氨基磷酸酯。

2-tert-Butyldiphenylsilylmethyl-substituted aziridine and the corresponding azetidine reacted efficiently with nitriles and carbonyl substrates to generate imidazoline, oxazolidine, and tetrahydropyrimidine products. The azetidine rearranged efficiently to the pyrrolidine skeleton involving migration of silicon under BF3.Et2O conditions. The tert-butyldiphenylsilylmethyl function, latent to CH2OH group
