Olefin cross-metathesis (CM) provides a short and convenient entry to diverse trans-gamma-aminoenones. When exposed to either acid or Heck arylation conditions, these intermediates are converted to mono-, di-, or trisubstituted pyrroles. The value of this chemistry is demonstrated by its application to the tetrasubstituted pyrrole subunit of Atorvastatin.

A photochemical approach to polysubstituted heterocycles using UV-induced alkene isomerization is described. The method allows for the synthesis of disubstituted furans and pyrroles under mild and neutral conditions and also provides access to a class of trisubstituted furans pertinent to natural-product synthesis. The method has broad functional-group tolerance and many richly decorated heterocycles
