Paragraph 0046; 0049-0050, (2014/09/30)
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.

Conceptually different: This allyltransfer reaction is catalyzed by Lewis acids (LAs) and proceeds atom-economically by disproportionation of the carbonyl groups through organized oxonia-Cope transition states (see scheme). A stereoselective [n+4] ring enlargement leads to a variety of macrolides with 9- to 16-membered rings. Copyright
