Ligand effects on the stereochemistry of Stille couplings, as manifested in reactions of Z-alkenyl halides

Unexpected losses in stereochemistry from Stille reactions involving Z-alkenyl halides have been shown to be ligand dependent. A new set of reaction conditions has been developed that, in most cases, leads to highly stereoselective cross-couplings under mild conditions, along with improved yields.

A Revised Modular Approach to (?)-trans-Delta8-THC and Derivatives Through Late-Stage Suzuki?Miyaura Cross-Coupling Reactions

A revised modular approach to various synthetic (?)-trans-Delta8-THC derivatives through late-stage Suzuki?Miyaura cross-coupling reactions is disclosed. Ten derivatives were synthesized allowing both sp2- and sp3-hybridized cross-coupling partners with minimal beta-hydride elimination. Importantly, we demonstrate that a para-bromo-substituted THC scaffold for Suzuki?Miyaura cross-coupling reactions has been initially reported incorrectly in recent literature.

Palladium-Catalyzed Umpolung Type-II Cyclization of Allylic Carbonate-Aldehydes Leading to 3-Methylenecycloalkanol Derivatives

Palladium-catalyzed umpolung type-II cyclization of allylic carbonate-aldehydes leading to 3-methylenecycloalkanol derivatives was developed. The formate reductant was effective for the cyclization without causing a reduction of the eta3-allylpalladium intermediate. One-pot decarboxylative allylation of aldehyde-containing malonate with 2-[(acetyloxy)methyl]-2-propenyl methyl carbonate followed by the cyclization of the allyl acetate-aldehyde formed in situ was also achieved. The high diastereoselectivities observed in the cyclization of branched substrates indicates that a chair-chair transition state should be involved. Based on the presumed transition state, we could predict the enantioselectivity of the cyclization using SEGPHOS as a chiral diphosphine ligand and obtain optically active alcohols in up to 95:5 er. (Figure presented.).

Heterolytic activation of dihydrogen by platinum and palladium complexes

Wide bite angle diphosphine ligands were used to prepare [(diphosphine)M(2-(diphenylphosphino)pyridine)]2+ complexes (M = Pd, Pt). Except for the ligand with the largest bite angle, 2-(diphenylphosphino) pyridine coordinates in a bidentate mode leading to bis-chelate complexes. In the case of Xantphos (9,9-dimethyl-4,5-bis(diphenylphosphino)-xanthene, betan = 111) two types of complexes are formed, in which 2-(diphenylphosphino)pyridine coordinates in a mono- or bidentate fashion, respectively. The crystal structures of three of the Pt complexes were determined. The X-ray crystal structure of [(Xantphos)-Pt(2-(diphenylphosphino) pyridine)]2+ shows that Xantphos coordinates in a tridentate P,O,P fashion. Under dihydrogen pressure, the pyridyl moiety in the platinum complexes can de-coordinate to provide a vacant coordination site at the metal center. Furthermore it can act as an internal base to assist the heterolytic cleavage of dihydrogen. The reaction yields a platinum hydride with a protonated pyridine moiety in close proximity to one another. The structure as well as the reactivity of the complexes towards dihydrogen is governed by the steric requirements of the diphosphines. The crystal structure of [(dppf)PtH(2- (diphenylphosphino)pyridinium)](OTf)2 has been determined. Palladium complexes containing DPEphos or Xantphos decompose under dihydrogen pressure. In the case of dppf slow heterolytic splitting of dihydrogen occurs to form the hydride complex [(dppf)PdH(2-(diphenylphosphino)pyridinium)](OTf)2 which contains a protonated 2-(diphenylphosphino)pyridine ligand. In solution, this compound slowly undergoes P-C bond cleavage of the 2-(diphenylphosphino) pyridine ligand to form [(dppf)Pd(PHPh2)(eta1-C 5H4NH)](OTf)2. When the 6-methyl-2- pyridyldiphenylphosphine ligand is used, the reaction of the palladium complex with dihydrogen is very fast and the hydride complex immediately rearranges to the diphenylphosphino compound resulting from P-C bond cleavage.

Process for the preparation of secondary amines

N,N-disubstituted amines in which the amino nitrogen atom is bound to the carbon atom of an aromatic ring disubstituted in the positions ortho to the carbon atom, are prepared by allowing a primary amine and a compound in which an ortho, ortho-disubstituted aromatic compound carrying a nucleofuge substituent, to react in a basic environment in the presence of a catalytic palladium(0) complex and a ligand, the ratio of palladium complex to ligand being greater than at least 1:1. A typical embodiment involves the reaction of 2-methyl-6-ethylphenyl-trifluoromethylsulfonate and (S)-1-methoxy-2-aminopropane in the presence of bis(dibenzylideneacetone)palladium, tri-tert.-butylphosphine, and sodium tert.-butoxide to yield (S)-N-(1-methoxyprop-2-yl)-2-methyl-6-ethylphenylamine.

Ligand exchange as the first irreversible step in the nickel-catalyzed cross-coupling reaction of grignard reagents

Mechanistic studies of the Ni-catalyzed cross-coupling reaction of Grignard reagents through analysis of kinetic isotope effects and theoretical calculations indicated that the product-to-substrate ligand exchange process is the first irreversible step and affects the turnover efficiency and selectivity of the reaction. On the other hand, the oxidative addition step is the first irreversible step in Pd catalysis. This finding has useful implications for the development of efficient Ni catalysis and also illustrates the importance of the catalyst turnover step that has so far received less attention than subsequent catalytic steps.
