The reaction of AlBui3 with the title compounds was investigated.The reductive rearrangement of 2-ethoxy-4-alkyl-2,3-dihydrofurans proceeds in the same way as that of the corresponding dihydropyran compounds although a complete lack of stereocontrol was observed.On the basis of the experimental results obtained, a likely mechanism for this reductive rearrangement is suggested.

Oxopropenylation of alkylmagnesium halides 4 by 3-(trimethylsilyloxy)acroleins 3 selectively yields the (E)-isomers of α,β-unsaturated aldehydes such as 4-phenyl-2-butenals 9, 3-cyclopropylpropenals 10, 3-cyclohexylpropenals 11, 3-(3-menthyl)propenals 12, and 2,5-hexadienals 13. 3-Hydroxyenolsilylethers 6 are isolated when allylmagnesium chloride is used as carbon nucleophile; to conclude, the reaction primarily involves nucleophilic addition of the Grignard reagent at the aldehyde carbon of the acrolein 3.
