multicomponent reaction from various N-methylisoquinolium or flavylium salts and 4-hydroxycoumarins or dimedone in acetone. Purification of the final products by recrystallization in ethyl acetate/methylene chloride or by column chromatography allowed easy isolation of nine compounds of each array. Preliminary studies indicated that some of the prepared compounds exhibit redox switching, photochromic
报道了一种用于制备含季碳三氮杂三环和螺吡喃的平行溶液相文库的实用方案。目标化合物是通过Et(3)N介导的多组分反应从丙酮中的各种N-甲基异喹啉盐或黄酮盐和4-羟基香豆素或二甲酮以中等至优异的产率获得的。通过在乙酸乙酯/二氯甲烷中重结晶或通过柱色谱法纯化最终产物,可以容易地分离出每种阵列的九种化合物。初步研究表明,某些制备的化合物具有氧化还原转换,光致变色和热致变色特性。
