p-Methoxyphenylimines obtained from enolizable aldehydes react in the absence of catalysts at room temperature with β-keto carboxylic acids through a decarboxylative Mannich reaction. The Mannich products were obtained with a high degree of anti selectivity. By use of chiral oxygen-containing aldehydes, operationally simple access to aminohydroxylated polyketide substructures is possible.
由可烯醇化醛获得的对甲氧基苯基亚胺在没有催化剂的情况下在室温下通过脱羧曼尼希反应与 β-酮羧酸反应。以高度的抗选择性获得曼尼希产物。通过使用手性含氧醛,可以在操作上简单地获得氨基羟基化聚酮化合物亚结构。
