Application of the Mannich reaction to 3,7-dibromotropolone gave 3,7-dibromo-5-morpholinomethyltropolone, from which 5-hydroxymethyl and 5-formyl derivatives were derived. It was found that the hydroxymethyl group of 3,7-dibromo-5-hydroxymethyltropolone can be easily displaced, and that 3,7-dibromo-5-formyltropolone has the characteristics of an ordinary aldehyde and reacts with ketones and malonic
曼尼希反应对 3,7-dibromotropolone 的应用得到 3,7-dibromo-5-morpholinomethyltropolone,从中衍生出 5-羟甲基和 5-甲酰基衍生物。发现3,7-二溴-5-羟甲基托酚酮的羟甲基很容易被置换,3,7-二溴-5-甲酰托酚酮具有普通醛的特性,能与酮类和丙二酸反应。
