We have studied the ring opening of nonactivated amino aziridines 1 by water under acidic conditions. Depending on the acid used, amino aziridines are cleaved at C-3 or C-2 with high regioselectivity, and total stereoselectivity, affording chiral 2,3-diaminoalkan-1-ols 3 or 1,3-diaminoalkan-2-ols 4 in high yield.
我们已经研究了在酸性条件下水对非活化氨基氮丙啶1的开环作用。根据所用酸的不同,氨基氮丙啶在C-3或C-2处具有较高的区域选择性和总立体选择性,可得到2,3-二氨基烷基-1-醇3或1,3-二氨基烷基-2-醇4的手性。高产。
