Mono- and dipalladium movement on the pi-conjugated five-carbon chain

We prepared new mono- and dipalladium complexes containing a highly conjugated pentadiynyl ligand where the palladium movement to the C5 position with the bonding rearrangement provided the first cumulenyl-type complexes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C52H43Cl3O3Pd2, you can also check out more blogs about52522-40-4

A photoinduced Wolff rearrangement/Pd-catalyzed [3+2] cycloaddition sequence: An unexpected route to tetrahydrofurans

A novel sequential reaction that combines a visible light-induced Wolff rearrangement of alpha-diazoketones and a Pd-catalyzed [3+2] cycloaddition of vinyl cyclopropanes with the resulting ketenes is described in this work. Selective O-allylic alkylation was observed over C-allylic alkylation, which unexpectedly led to a series of highly functionalized tetrahydrofurans with high efficiency (20 examples, 58-99% yields).

Carbenylative Amination and Alkylation of Vinyl Iodides via Palladium Alkylidene Intermediates

Most palladium-catalyzed reactions involving insertion of alkylidenes with alpha-hydrogens undergo beta-hydride elimination from alkylpalladium(II) intermediates to form alkenes. Vinyl iodides were shown to generate eta3-allylpalladium intermediates that resist beta-hydride elimination, preserving the sp3 center adjacent to the carbene moiety. Acyclic stereocontrol (syn/anti) for carbenylative amination and alkylation reactions was low, suggesting a lack of control in the migratory insertion step. Highly hindered carbene precursors inexplicably led to formation of Z-alkenes with high levels of stereocontrol.

Stereoselective allyl enol carbonates for the synthesis of chiral aldehydes bearing all carbon quaternary stereocenters via the decarboxylative asymmetric allylic alkylation (DAAA)

A stereoselective synthesis of carbonates derived from 3-hydroxy-2-aryl acrylates was devised that can form the Z- or E-stereoisomer in very high Z/E ratios (50:1 and 1:99, respectively). The stereochemical outcome depends on the choice of base, addition of TMEDA and reaction temperature. The Z- and E-stereoisomers have different reactivities towards the DAAA reaction, with the E-stereoisomer displaying both greater reactivity and enantiodifferentiation with chiral ligands. The DAAA of E-stereoisomer analogues takes place in excellent yields ranging from 96-99% and enantioselectivities ranging from 42-78% ee.

Development of the first P-stereogenic PCP pincer ligands, their metallation by palladium and platinum, and preliminary catalysis

The potentially tridentate P-stereogenic [P*CP*] ligands 1,3-{(bis[(tert-butyl)(phenyl)phosphino]methyl)-benzene and 1,3-{(bis[(tert-butyl)(phenyl) phosphino]methyl})1-2-bromobenzene have been synthesized as the protected phosphine-borane adducts. Deprotection with a secondary amine affords the free phosphine ligand which can be metallated by Pd and Pt with standard metal synthons. Two of the resultant [P*CP*] metal complexes have been characterized by X-ray crystallography. The complexes exhibit a C2 symmetric environment about the remaining binding site of the square-planar center, with t-Bu groups filling two quadrants of the open site. The Pd complexes can be converted by use of a Ag salt to the analogous aquo complex, which is catalytically active in the aldol condensation of methyl 2-isocyanoacetate and benzaldehyde. Preliminary results and comparisons with previously reported catalysts with more distal C-stereogenicity are presented.

A concise approach for central core of trigolutes: Total synthesis of trigolute B and 3-epi-trigolute B and analogues

A concise approach comprising a combination of the Pd- or Ir-catalyzed Tsuji-Trost allylation and olefin dihydroxylation/acid catalyzed lactonization has been developed to construct the central spirolactone core of trigolutes with the requisite functional groups. A large number of analogues of trigolute B have been synthesized. Furthermore, the synthesis of both (¡À)-trigolute B and (¡À)-3-epi-trigolute B has been accomplished in 4?5 steps from easily accessible building blocks.

Design and synthesis of alpha-carboxy nucleoside phosphonate analogues and evaluation as HIV-1 reverse transcriptase-targeting agents

The synthesis of the first series of a new class of nucleoside phosphonate analogues is described. Addition of a carboxyl group at the alpha position of carbocyclic nucleoside phosphonate analogues leads to a novel class of potent HIV reverse transcriptase (RT) inhibitors, alpha-carboxy nucleoside phosphonates (alpha-CNPs). Key steps in the synthesis of the compounds are Rh-catalyzed O-H insertion and Pd-catalyzed allylation reactions. In cell-free assays, the final products are markedly inhibitory against HIV RT and do not require phosphorylation to exhibit anti-RT activity, which indicates that the alpha-carboxyphosphonate function is efficiently recognized by HIV RT as a triphosphate entity, an unprecedented property of nucleoside monophosph(on)ates.

An efficient method for the enantioselective construction of tertiary 1,3-diols via Pd-catalyzed asymmetric allylic cycloaddition of vinyloxetanes with an abundant feedstock, formaldehyde, is developed. Using the palladium complex generated in situ from Pd2(dba)3¡¤CHCl3 and phosphoramidite L3 as a catalyst under mild conditions, the process allows one to convert racemic 2-substituted 2-vinyloxetanes (1) to the corresponding 1,3-dioxanes (2) as methylene acetal protected tertiary 1,3-diols in high yields with good to excellent enantioselectivities.
