N,N-Dialkyltrimethylsilylamines were used for the synthesis of a series of pentamethinium salts starting from 2,6-disubstituted or 2,4,6-trisubstituted pyrylium salts, N-substituted 5-aminopenta-2,4-dienals or N-substituted 5-aminopenta-2,4-dien-1-ones. The reactions proceed smoothly under mild conditions, furnishing the desired products in good yields.
研究人员利用 N,N-二烷基三甲基硅胺从 2,6- 二取代或 2,4,6- 三取代的吡啶鎓盐、N-取代的 5- 氨基戊-2,4-二烯或 N-取代的 5- 氨基戊-2,4-二烯-1-酮开始,合成了一系列五甲基鎓盐。反应在温和的条件下顺利进行,并能以良好的收率获得所需的产品。
