A series of new isoprenyl-thiourea and urea derivatives were synthesized by the reaction of alkyl or arylisothiocyanate or isocyanate and primary amines. The structures of the compounds were established by 1H NMR, 13C NMR, MS, HRMS and elemental analysis. The newcompounds were screened for in vitro antimicrobial activity against seven strains representing different types of gram-positive and gram-negative
通过烷基或芳基异硫氰酸酯或异氰酸酯与伯胺的反应,合成了一系列新的异戊二烯基-硫脲和脲衍生物。化合物的结构通过1 H NMR,13 C NMR,MS,HRMS和元素分析确定。对新化合物进行了体外筛选对代表不同类型革兰氏阳性和革兰氏阴性细菌的七种菌株的抗菌活性。超过三分之一的合成化合物显示出对测试菌株的可变抑制活性。对于具有3-甲基-2-丁烯基,异丁基或异戊基和具有吸电子取代基的芳环的那些硫脲类似物,发现了最佳的抗菌活性。还对新化合物进行了抗肿瘤活性的初步筛选。芳环中高度亲脂性基团和吸电子基团的存在增强了合成化合物的抗癌活性,在大多数情况下显示出比对照更高的活性。

A slightly adapted catalyst system has been successfully applied in the directamination of primary and secondaryalcohols. Moreover, the applicability to diols has been shown, giving high selectivity towards the primary diamines. It was found that the Ru/P ratio as well as the amount of ammoniaused are highly important in this system, especially for higher substrate loadings. The catalyst was employed
