Octadienyl carbonates 5 provide cyclic 1,4-dienes 6 when treated with RhI complexes (1-10 mol-percent) at 80 deg C.Similar cyclization of cyclohexenyl acetate 8 affords cis-fused hexahydroindene 9.Analogues ring closures of nonadiene carbonate 10 yield preferably the cis-divinylpyrrolidine 11 with RhI catalysis but the trans-isomer 12 when catalyzed by Pd0.Azaoctadienyl carbonate 5a undergoes elimination with
