original, effective approach to the synthesis of natural and synthetic 5Z,9Z-dienoic acids in high yields (61-67%) and with high selectivity (>98%) was developed. The approach is based on the use of the new intermolecular catalytic cross cyclomagnesiation of terminal aliphatic and oxygenated 1,2-dienes upon treatment with Grignard reagents in the presence of the Cp2TiCl2 catalyst. High activity of (5Z
开发了一种新颖,有效的合成天然和合成5Z,9Z-二烯酸的方法,产率高(61-67%),选择性高(> 98%)。该方法是基于在Cp2TiCl2催化剂存在下用格氏试剂处理后,使用末端脂族和含氧1,2-二烯的新型分子间催化交叉环氧化作用。阐明了(5Z,9Z)-5,9-二十二碳二烯酸作为人拓扑异构酶I抑制剂在0.1μM以上的浓度下的高活性。
