The combined use of aluminum tris(2,6-diphenylphenoxide) (ATPH) and lithium 2,2,6,6-tetramethylpiperidide (LTMP) has proven to be effective for the mixed crossed aldol condensation between conjugated esters and various aldehydes. An example is shown in Equation (1).
三(2,6-二苯基苯氧基铝)(ATPH)和2,2,6,6-四甲基哌啶锂(LTMP)的组合使用已被证明对共轭酯和各种醛之间的混合交叉羟醛缩合有效。等式(1)中示出了一个例子。
