A variety of 2-amino-3-arylpropan-1-ols, anti-2-amino-3-aryl-3-methoxypropan-1-ols and anti-2-amino-1-arylpropan-1,3-diols were prepared selectively through elaboration of trans-4-aryl-3-chloro-β-lactams. In addition, a number of 2-(azidomethyl)aziridines was converted into novel 2-[(1,2,3-triazol-1-yl)methyl]aziridines by Cu(I)-catalyzed azide-alkyne cycloaddition, followed by microwave-assisted, regioselective ring opening by dialkylamine towards 1-(2,3-diaminopropyl)-1,2,3-triazoles. Although most of these compounds exhibited weak antiplasmodial activity, six representatives showed moderate antiplasmodial activity against both a chloroquine-sensitive and a chloroquine-resistant strain of Plasmodium falciparum with IC50-values of ≤25 μM.
一种多样的2-氨基-3-芳基丙醇,反-2-氨基-3-芳基-3-甲氧基丙醇和反-2-氨基-1-芳基丙烷-1,3-二醇通过精心设计的反式-4-芳基-3-氯-β-内酰胺的改进而选择性地制备。此外,一些2-(叠氮甲基)环氧丙烷经Cu(I)催化的叠氮-炔烃环加成反应转化为新型的2-[(1,2,3-三氮唑-1-基)甲基]环氧丙烷,随后通过二烷基胺的微波辅助、区域选择性环开启反应朝向1-(2,3-二氨基丙基)-1,2,3-三氮唑。尽管大多数这些化合物表现出弱的抗疟活性,但有六个代表性化合物对氯喹敏感和氯喹耐药株的疟原虫Plasmodium falciparum均表现出中等抗疟活性,IC50值≤25 μM。
