A direct acid catalyzed intermolecular electrocyclic rearrangement process for the preparation of linear and cyclic homoallylic ester and amides. A one step intermolecular electrocyclic rearrangement process includes the step of reacting a beta, gamma-unsaturated aldehyde or ketone, in which the beta, gamma-unsaturation is not part of an aromatic ring, with another aldehyde or a secondary aldimine in the presence of an acid.
