Highly stereoselective synthesis of (1E)-2-melethyl-1,3-dienes by palladium-catalyzed trans-selective cross-coupling of 1,1-dibromo-1-alkenes with alkenylzine reagents

Ligand control: The use of Pd complexes containing tBu3P or nitrogen-heterocyclic carbene (NHC) ligands almost completely prevents stereoisomerization, thereby permitting an efficient and selective methylation and higher alkylation of (Z)-2-bromo-1,3-dienes (see scheme, dba = trans,trans-dibenzylideneacetone).

Palladium-catalyzed cyanomethylation of aryl halides through domino Suzuki coupling-isoxazole fragmentation

A one-pot protocol for the cyanomethylation of aryl halides through a palladium-catalyzed reaction with isoxazole-4-boronic acid pinacol ester was developed. Mechanistically, the reaction proceeds through (1) Suzuki coupling, (2) base-induced fragmentation, and (3) deformylation as shown by characterization of all postulated intermediates. Under optimized conditions (PdCl2dppf, KF, DMSO/H2O, 130 C) a broad spectrum of aryl bromides could be converted into arylacetonitriles with up to 88% yield.

Aromatic amine N-oxide organometallic compounds: Searching for prospective agents against infectious diseases

In search of prospective agents against infectious diseases, 1,1?-bis(diphenylphosphino)ferrocene pyridine-2-thiolato-1-oxide M(II) hexafluorophosphate compounds [M(mpo)(dppf)](PF6), where M = palladium or platinum, were synthesized and fully characterized in the solid state and in solution using experimental and DFT computational techniques. The compounds are isomorphous and the M(II) transition metal ions are in a nearly planar trapezoidal cis-coordination bound to the pyridine-2-thiolato-1-oxide (mpo) and to the 1,1?-bis(diphenylphosphino)ferrocene molecules, both acting as bidentate ligands. Both compounds showed high cytotoxic activity on Trypanosoma cruzi and Mycobacterium tuberculosis (MTB) and acceptable selectivities towards MTB, but good to excellent selectivity index values as anti-T. cruzi compounds. The inclusion of the ferrocene moiety (dppf ligand) improved the selectivity towards the parasite when compared to the previously reported [M(mpo)2] complexes. Related to the probable mechanism of action of the complexes, molecular docking studies on modelled T. cruzi NADH-fumarate reductase (TcFR) predicted that both be very good inhibitors of the enzyme. The effect of the compounds on the enzyme activity was experimentally confirmed using T. cruzi protein extracts. According to all obtained results, both [M(mpo)(dppf)](PF6) compounds could be considered prospective anti-trypanosomal agents that deserve further research.

Stereochemistry of eudesmane cation formation during catalysis by aristolochene synthase from Penicillium roqueforti

The aristolochene synthase catalysed cyclisation of farnesyl diphosphate (1) has been postulated to proceed through (S)-germacrene A (3). However, the active site acid that reprotonates this neutral intermediate has so far proved difficult to identify and, based on high level ab initio molecular orbital and density functional theory calculations, a proton transfer mechanism has recently been proposed, in which proton transfer from C12 of germacryl cation to the C6,C7-double bond of germacryl cation (2) proceeds either directly or via a tightly bound water molecule. In this work, the stereochemistry of the elimination and protonation reactions was investigated by the analysis of the reaction products from incubation of 1 and of [12,12,12,13,13,13- 2H6]-farnesyl diphosphate (15) with aristolochene synthase from Penicillium roqueforti (PR-AS) in H2O and D2O. The results reveal proton loss from C12 during the reaction and incorporation of another proton from the solvent. Incubation of 1 with PR-AS in D2O led to the production of (6R)-[6-2H] aristolochene, indicating that protonation occurs from the face of the 10-membered germacrene ring opposite the isopropylidene group. Hence these results firmly exclude proton transfer from C12 to C6 of germacryl cation. We propose here Lys 206 as the general acid/base during PR-AS catalysis. This residue is part of a conserved network of hydrogen bonds, along which protons could be delivered from the solvent to the active site.

Construction of the DEF-ring system of nogalamycin and menogaril via an efficient Suzuki-Miyaura reaction

A new approach to the total synthesis of anthracycline natural products, nogalamycin and menogaril, was explored. The goal was to enable late-stage introduction of the EF-ring segment. The new synthetic route has been developed through strategic application of a Suzuki-Miyaura reaction as the key step, which coupled the EF-ring segment with the D-ring to give a 1,1?-disubsitituted alkene in good yield under biphasic conditions. Further manipulation of the coupling product completed the construction of the DEF-ring system.

Palladium-catalyzed cross-coupling reactions with zinc, boron, and indium exhibiting high turnover numbers (TONs): Use of bidentate phosphines and other critical factors in achieving high TONs

Summary: Palladium-catalyzed reactions of unsaturated organozincs with aryl or alkenyl iodides can exhibit turnover numbers (TONs) over 105 (>70% product yields). Under the conditions employed, Zn, B, and In appear to be the three most favorable metals, followed by Al(Zn) and Zr(Zn), whereas TONs observable with Sn, Cu, and Mn have been significantly lower.

Total synthesis of marinomycins A-C and of their monomeric counterparts monomarinomycin A and iso-monomarinomycin A

Marinomycins A-C (1-3), and their monomeric analogues monomarinomycin A (m-1) and iso-monomarinomycin A (m-2), were synthesized by a convergent strategy from key building blocks ketophosphonate 5, aldehyde 6, and dienyl bromide carboxylic acid 7. The first attempt to construct marinomycin A [1, convertible to marinomycins B (2) and C (3) by light] by direct Suzuki-type dimerization/ cyclization of boronic acid dienyl bromide 4 led to premature ring closure to afford, after global desilylation, monomarinomycin A (m-1) and iso-monomarinomycin A (m-2) in good yield and only small amounts (?2%) of the desired product. A subsequent stepwise approach based on Suzuki-type couplings improved considerably the overall yield of marinomycin A (1), and hence of marinomycins B (2) and C (3). Alternative direct dimerization approaches based on the Stille and Heck coupling reactions also led to monomarinomycins A (m-1 and m-2), but failed to deliver useful amounts of marinomycin A (1).

Straightforward and Regioselective Access to Unsaturated alpha-Benzyl Butyrolactones

The efficient preparation of various substituted alpha-benzyl unsaturated butyrolactones is described. The palladium-mediated C?C bond formation that uses alpha-bromomethylbutenolide and boron derivatives as coupling partners accounts for the key step of this synthetic approach. Our strategy exclusively affords the endocyclic adduct and represents an alternative to Heck-type reactions. The synthesis and characterization of two nostoclide analogues has also been reported.
