titleOfInvention | Process for preparing alpha, beta-unsaturated aldehydes |
abstract | A process for preparing α,β-unsaturated aldehydes of the general formula (I)in which R', R<sup>2</sup> and R" are independently a hydrogen atom, or an alkyl or alkenyl group with or without being substituted with a lower acyloxy group. The aldehyde of the general formula (I) is prepared by reaction between an allylic chloride of the following general formula (Ila)in which R<sup>1</sup>, R<sup>2 </sup>and R<sup>3</sup> have, respectively, the same meanings as defined above, and an amide oxide selected from the group consisting of tri(lower alkyl)amine N-oxides of the formula,in which R<sup>4</sup> represents a lower alkyl group having from 2 to 4 carbon atoms, and N-lower alkylmorpholine N-oxides of the following formulain which R<sup>5</sup> represents a lower alkyl group having from 1 to 4 carbon atoms. Alternatively, the aldehyde of the formula (I) is obtained by reaction between an allylic chloride of the following general formula (IIb)in which R<sup>1</sup>, R<sup>2</sup> and R<sup>3</sup> have, respectively, the same meanings as defined above, and an amine oxide selected from the group consisting of tri(lower alkyl)amine N-oxides of the formula,in which R<sup>4</sup> has the same meaning as defined above, and N-lower alkylmorpholine N-oxides of the following formulain which R<sup>5</sup> has the same meaning as defined above, in the presence of an alkali metal iodide or a copper halide. |
