摘要：

Octadienyl carbonates 5 provide cyclic 1,4-dienes 6 when treated with Rh(I) complexes (1-10 mol-%) at 80-degrees. Similar cyclization of cyclohexenyl acetate 8 affords cis-fused hexahydroindene 9. Analogous ring closures of nonadienyl carbonate 10 yield preferably the cis-divinylpyrrolidine 11 with Rh(I) catalysis but the trans-isomer 12 when catalyzed by Pd0. Azaoctadienyl carbonate 5a undergoes elimination with [RhH(PPh3)4] (5 mol-%, 80-degrees) in MeCN giving acyclic triene 7.
