The radicalcyclizations of bromo ketals derived from the Birch-alkylation products of α-tetralones are described. The carboncarbon bond formation proceeds in a regio- and stereoselective way. The intra- and intermolecular trapping behavior was also explored.

Abstract The synthesis of the tetracyclic mainframe containing the caged ketalic backbone of saudin was accomplished through a straight forward sequence starting from α-tetralone. The sequence included the stereoselective preparation of a key epoxy alcohol that allowed, by means of an intramolecular radical cyclisation, the total control of the relative stereochemistry of four consecutive chiral centers
