The low yields attained for the reactions shown in Scheme 3 call into doubt the usefulness of the syn-oxidative polycyclization under the published PCC-conditions for preparative purposes. However, the palette of possible oxidation reagents is by no means exhausted by PCC. Valuable ideas for a solution of the problem come from the work of Kennedy et al. with Re207 as an oxidizing agent for oxidative olefin cyclization. [6] As shown in Scheme 4 Keinan et al. [10] applied Re207 successfully in an iterative oxidative-olefin-cyclization sequence leading to oligo-tetrahydrofurans (20 -> 21 -> 22). [Pg.231]
