Intramolecular cyclization of a diruthenium complex: insight into the mechanism of heteroatom-directed intramolecular C-H/olefin coupling reactions.

Complex 2, synthesized by the reaction of {(C5H4N)(μ2-η(5):η(1)-C9H5)}Ru3(CO)9 (1) with 1,5-hexadiene, could further transform to another diruthenium complex 3via intramolecular carbometalation. The results are relevant to the mechanism of transition-metal catalyzed heteroatom-directed intramolecular C-H/olefin coupling reactions.

Cobalt-catalyzed intramolecular C-N and C-O cross-coupling reactions: synthesis of benzimidazoles and benzoxazoles.

Cobalt(ii)-complex catalyzes efficiently the intramolecular C-N and C-O cross-couplings of Z-N'-(2-halophenyl)-N-phenylamidines and N-(2-bromophenyl)benzamides to afford the corresponding substituted benzimidazoles and benzoxazoles in the presence of K(2)CO(3) at moderate temperature. The protocol is general, air stable and affords the products selectively in moderate to high yield.

Anodic cyclization reactions: the total synthesis of alliacol a.

An anodic cyclization-Friedel Crafts alkylation strategy has been used to rapidly assemble the core ring system of alliacol A and to complete a formal total synthesis of the natural product. The anodic cyclization reaction was used to effect the coupling of a nucleophilic furan ring to the normally nucleophilic carbon of a silyl enol ether. The substrate for this initial cyclization reaction co...
