The simplest aldol condensation reaction is illustrated below:

WebSeveral amides were obtained in high yields by an efficient method from the corresponding imines which are readily prepared from aldehydes. This procedure involves the oxidation of aldimines with m-CPBA and BF 3 ·OEt 2. In this reaction, the product is strongly influenced by the electron releasing capacity of the aromatic substituent (Ar). G. WebAldehydes could be converted to esters in one step.
