Novel structural rearrangements induced by metal-metal interactions in ruthenium(II) ruthenocenyl- and (pentamethylruthenocenyl)acetylide complexes, RcC?CRuL2(eta5-C5R5) and Rc?C?CRuL2(eta5-C5R5)

The reaction of RcC?CH [Rc = (eta5-C5H5)Ru(eta5-C 5H4)] with RuCIL2(eta5-C5R5) [R = H or Me; L2 = 2PPh3 or Ph2PCH2CH2PPh2 (dppe)] in the presence of NH4PF6 and subsequent treatment with base gave Ru(II) ruthenocenylacetylide complexes RcC?CRuL2(eta5-C5R5) in good yields. In a similar manner, the pentamethylruthenocene analogues, Rc?C?CRuL2(eta5-C5R5) [Rc? = (eta5-C5Me5)Ru(eta5-C 5H4)], were also prepared. Cyclic voltammograms of the complexes showed two reversible one-electron-oxidation processes, consisting of the processes [Ru(II)Ru?(II] to [Ru(III)Ru?(II] and then to [Ru(III)Ru?(III)]. Chemical oxidation of the complexes induced novel structural rearrangement. The two-electron oxidation of complex RcC?CRu(PPh3)2(eta5-C5H 5) afforded a kind of allenylidene complex, a cyclopentadienyl-idenethylidene complex, [(eta5-C5H5)Ru{mu-eta 6:eta1-C5H4C=C}Ru(PPh 3)2(eta5-C5H5)] 2+, in 90% yield. The one-electron oxidation of Rc?C?CRu(PPh3)2(eta5-C 5H5) gave the vinylidene complex (Rc?CH=C)Ru(PPh3)2(eta5-C 5H5) in 62% yield, while the two-electron oxidation led to the fulvene-vinylidene complex [(eta6-C5Me4CH2)Ru{mu-eta 5:eta1-C5H4CH=C}Ru(PPh 3)2(eta5-C5R5)] 2+ by an intramolecular hydrogen transfer in 59% yield.

Enantioselective Total Synthesis of (+)-Dihydro-beta-erythroidine

Erythrina alkaloids represent a rich source of complex polycyclic, bioactive natural products. In addition to their sedative and hypotensive effect, their curare-like activity and structural framework have made them attractive targets for synthetic and medicinal chemists. (+)-Dihydro-beta-erythroidine (DHbetaE), the most potent nicotine acetylcholine receptor antagonist (nAChR) of the Erythrina family, is synthesized for the first time in 13 steps from commercially available material.

A Novel Jaspine B-Ceramide Hybrid Modulates Sphingolipid Metabolism

A new sphingolipid hybrid molecule was designed to assemble, within a tail-to-tail double-chain structure, the ceramide hydrophilic moiety and the tetrahydrofuran pharmacophore of jaspine B, a natural product known to interfere with sphingolipid metabolism. This compound was prepared through acylation of sphingosine with a jaspine B derivative bearing a COOH group in the terminal position of the aliphatic backbone. This new hybrid molecule was evaluated for its capacities to affect melanoma cell viability and sphingolipid metabolism. While retaining the cytotoxicity of ceramide itself, this compound was shown to lower the sphingomyelin cellular levels and significantly enhance the production of sphingosine-1-phosphate, thus representing a novel sphingolipid metabolism modulator.

Concise synthesis of broussonone A

A concise and expeditious approach to the total synthesis of broussonone A, a p-quinol natural compound, has been developed. The key features of the synthesis include the Grubbs II catalyst mediated cross metathesis of two aromatic subunits, and a chemoselective oxidative dearomatizationin the presence of two phenol moieties. Especially, optimization associated with the CM reaction of ortho-alkoxystyrenes was also studied, which are known to be ineffective for Ru-catalyzed metathesis reactions under conventional reaction conditions because ortho-alkoxy group could coordinate to the ruthenium center, resulting in the potential complication of catalyst inhibition.
