1) dihydroxybenzaldehyde
二羟基苯甲醛
1.
The synthetic yield of dimethyl hydroxybenzaldehyde and three dihydroxybenzaldehydes, via classical ReimerTiemann reaction, is generally very low (less 10%).
用经典的ReimerTiemann反应合成二甲基羟基苯甲醛和二羟基苯甲醛时产率(10%以下)很低。
2.
N-methyl-2-(3,4-dihydroxyphenyl) fullerene pyrrolidine was synthesized by the 1,3-dipolar cycloaddition reaction of fullerene(C60) and azomethine ylide(prepared from N-methylglycine and 3,4-dihydroxybenzaldehyde).
最佳反应条件为:n(C60)∶n(N-甲基甘氨酸)∶n(3,4-二羟基苯甲醛)=1∶2∶5,温度为95℃,反应时间为28 h,产率可达66%(以消耗的C60计)。
