| heal.abstract | Styrenes of general structure 5 undergo tandem radical cyclization to cis,cis-hydrophenanthrofurans 9, products which contain the carbocyclic skeleton of the morphine alkaloids. Vinylurethane 5E-NHCO(2)Et cyclizes to 9 alpha via the intermediate radical 7E-NHCO(2)Et in the chair-chair conformation. Cyclization of 5Z-NHCO(2)Et also gives predominantly 9 alpha instead of the expected 9 beta. This anomaly is attributed to the isomerization of 5Z to 5E at a rate competitive with that of cyclization. | en |
