A series of new enantiomerically pure and racemic 1,3-dioxolanes 1-8 was synthesized in good yields and short reaction times by the reaction of salicylaldehyde with commercially available diols using a catalytic amount of Mont K10. Elemental analysis and spectroscopic characterization established the structure of all the newly synthesized compounds. These compounds were tested for their possible antibacterial and antifungal activity. Biological screening showed that all the tested compounds, except 1, show excellent antifungal activity against C. albicans, while most of the compounds have also shown significant antibacterial activity against S. aureus, S. epidermidis, E. faecalis and P. aeruginosa.
合成了一系列新的对映体纯的和外消旋的1,3-二噁烷1-8,这些化合物通过香豆醛与市售二醇在催化量的Mont K10存在下反应,产率良好且反应时间短。元素分析和光谱表征确定了所有新合成化合物的结构。这些化合物被测试其可能的抗菌和抗真菌活性。生物筛选显示,除化合物1外,所有测试的化合物对白色念珠菌(C. albicans)表现出优异的抗真菌活性,而大多数化合物对金黄色葡萄球菌(S. aureus)、表皮葡萄球菌(S. epidermidis)、肠球菌(E. faecalis)和铜绿假单胞菌(P. aeruginosa)也表现出显著的抗菌活性。
