The use of donor-only silylmethylcyclopropanes in the Lewis acid promoted reaction with aldehydes to generate 2,5-disubstitutedtetrahydrofurans is described. The diastereoselectivity obtained in the product is very much dependent upon the temperature of the reaction.

The synthesis of 2,5-disubstituted tetrahydrofurans from donor silylmethylcyclopropanes (without bearing an acceptor function) is described. Their further elaboration via a wide range of synthetic transformations is presented to highlight the potential of this method and the resulting THFs as potential scaffolds for diversity-orientedsynthesis.
