medicinal chemistry and natural products. Herein, we report that an exceptionally simple and inexpensive FeII complex efficiently catalyzes the direct transformation of simple alkenes into unprotected amino alcohols in good yield and perfect regioselectivity. This new catalytic method was applied in the expedientsynthesis of bioactive molecules and could be extended to aminoetherification.

performed to understand the effect of different substituents on the phenyl ring of amide- and sulfonamide-based compounds that partially resemble the structure of well-known inhibitors such as B-13, D-e-MAPP as well as NOE. Our results suggest that the electronic effects of the substituents on phenyl ring in B-13 and D-e-MAPP analogues have negligible effects either in enhancing the inhibition potencies
在本研究中,我们描述了一系列基于酰胺和磺酰胺的化合物的设计和合成,这些化合物可作为重组酸和中性神经酰胺酶的抑制剂。在某些癌症模型中,抑制ceramidases可以诱导细胞凋亡并提高常规化学疗法的功效。B-13,酸性神经酰胺酶的体外先导抑制剂,最近已被证明对活细胞中的溶酶体酸性神经酰胺酶在较低的浓度和较短的治疗时间内实际上是无活性的,这表明已开发出了更有效的抑制剂。在这项研究中,已进行了详细的SAR研究,以了解不同取代基对部分类似于众所周知的抑制剂(例如B-13,D- e)的酰胺基和磺酰胺基化合物的苯环的影响。-MAPP以及NOE。我们的结果表明,在B-13和D- e - MAPP类似物中苯环上的取代基的电子效应在增强抑制能力或对aCDase的选择性高于对nCDase的选择性方面可忽略不计。然而,发现苯环上较长烷基链(n -Pr,n -Bu或t -Bu基)的疏水性和空间效应对于增强对aCDa
