Abstract Monoterpene derivatives are of great biological relevance in the pharmaceutical industry. In the present study, pyrrolidine derivative of a carvotacetone, 3-O-benzylcarvotacetone (1), and selected monoterpenes (3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone (3) and cis-piperitol (5)) were prepared to provide (R)-1-(4-(benzyloxy)-5-isopropyl-2-methylcyclohexa-1,3-dien-1-yl)-pyrrolidine (2),
摘要 单萜衍生物在制药工业中具有重要的生物学意义。在本研究中,一种 carvotacetone、3 - O -benzylcarvotacetone ( 1 ) 的吡咯烷衍生物和选定的单萜(3-hydroxy-2-isopropyl-5- methyl- p - benzoquinone ( 3 ) 和cis - piperitol ( 5 ))制备得到 ( R )-1-(4-(苄氧基)-5-异丙基-2-甲基环己-1,3-二烯-1-基)-吡咯烷( 2 ), 2-异丙基-5-甲基-3 ,6-dioxocyclohexa-1,4-dien-1-yl acetate ( 4 )、顺式-3-羟基胡椒酮 ( 6 ) 和香芹酚 ( 7 )。2的结构基于NMR和HRMS光谱数据确定。化合物4对真菌新型隐球菌具有活性,IC 50值 < 0.8 µg/mL。此外,该化合物4对耐甲氧西林金黄色葡萄球菌的IC
