Abstract
Abstractp‐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.
