英文摘要: In this paper, a bimolecular-cyclization reaction between two different bis(allene)s with at least one heteroatom as the tether under the catalysis of trans-[RhCl(CO)(PPh3)(2)] is described. This protocol provides an efficient entry to different heterocyclic 18.19-norsteroid-like scaffolds. The tri-cyclic product was formed highly selectively from the cyclization reaction of bis (2,3-butadienyl) sulfide with dimeth- yl 2-bis(2',3'-butadienyl)malonate, which sheds light on the mechanism involving the metalla-[4.3.0]-bicyclic intermediate formed by the cyclometallation of the terminal and the internal C=C bonds of each of the two allene moieties in 2-bis(2',3'-butadienyl)malonate.
