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

This paper reports several model studies that were necessary for the rational conception of a simple four-step synthesis (6 + (S)-74 → 81a–b → 83 87 → 89) (Scheme 11) of the carbonate derivative 8...
