o-Iodophenols and o-iodoaniline derivatives react with terminal alkynes under 1 atm of CO in the presence of pyridine and catalytic amounts of Pd(OAc)2 to generate coumarins and 2-quinolones, respectively, as the only products. Terminal alkynes bearing alkyl, aryl, silyl, hydroxyl, ester and cyano substituents are effective in these processes affording the desired products in moderate yields. The formation of coumarins and 2-quinolones in this process is in stark contrast with all previously described palladium-catalyzed reactions of o-iodophenols or o-iodoanilines with terminal alkynes and CO, which have afforded chromones and 4-quinolones. Moreover, under our reaction conditions terminal alkynes insert into the carbon-palladium bond instead of undergoing a Sonogashira-type coupling as confirmed by an isotope labeling experiment.

A new generation of PNP compounds bearing different diarylphosphine groups were prepared and used as ligands in palladium-catalysed Suzuki cross-coupling reactions. Rates of oxidative addition of iodobenzene to (PNP)Pd[o] complexes were measured using UV spectroscopy. Synergistic effects between the N- and P- substituents were identified and correlated in redox and catalytic chemistry.

The heavy-atom heterocycle Pd[Re2(CO)8(mu-SbPh2)(mu-H)]2 (5) has been synthesized by the palladium-catalyzed ring-opening cyclodimerization of the three-membered heterocycle Re2(CO)8(mu-SbPh2)(mu-H) (3). The Pd atom occupies the center of the ring. The Pd atom in 5 can be removed reversibly to yield the palladium-free heterocycle [Re2(CO)8((mu-SbPh2)(mu-H)]2 (6).

Stereoselective synthesis of 2-substituted dehydropiperidinones and their further transformation to variously disubstituted piperidine derivatives was achieved employing D-arabinopyranosylamine as the stereodifferentiating carbohydrate auxiliary. A domino Mannich-Michael reaction of 1-methoxy-3-(trimethylsiloxy)butadiene (Danishefsky’s diene) with O-pivaloylated arbinosylaldimines furnished N-arabinosyl dehydropiperidinones in high diastereoselectivity. Subsequent conjugate cuprate addition gave 2,6-cis-substituted piperidinones, while enolate alkylation furnished 2,3-trans-substituted dehydropiperidinones. Electrophilic substitution at the enamine structure afforded 5-nitro- and 5-halogen dehydropiperidinones of which the latter were applied in palladium-catalyzed coupling reactions. The absolute configuration of the obtained products was proven by NMR and X-ray structure analysis as well as by syntheses of the alkaloids (+)-coniine and (+)-dihydropinidine.

A collection of fourteen diphenylamine macrocyclic derivatives containing a peptide chain with different substituents was synthesized using a protocol of two Ugi four component reactions (Ugi-4CR) and a Buchwald-Hartwig macrocyclization. Their anti-inflammatory effects were assayed with an ear edema model using 12-O-tetradecanoylphorbol-13-acetate, while the activity of myeloperoxidase was determined to evaluate the index of leukocyte infiltration. Compound 5e had an ID50 of 0.18 muM per ear with a potency higher than that of the reference drugs indomethacin and celecoxib (0.24 and 0.91 muM per ear, respectively). Moreover, the cytotoxicity of the macrocycles was determined in two healthy cell lines, showing a low percentage of toxicity.

A method has been developed for the chemo- and stereoselective Suzuki-Miyaura cross-coupling of optically enriched gem-diboronyl compounds with various aryl bromides. Experimental evidence suggests that the Lewis acidity of the second boron group in these substrates plays a significant role in facilitating these otherwise challenging cross-coupling processes. beta-Diboronyl esters may be successfully cross-coupled in excellent yield and enantiomeric excess with prior conversion of the pinacol boronate to the corresponding trifluoroborate salt. In contrast, a substrate bearing a Weinreb amide can undergo direct coupling of the Bpin moiety, likely due to the stronger coordination of the more basic amide carbonyl group. The resulting optically enriched secondary boronate may be used in a second enantioselective cross-coupling to afford pharmaceutically relevant diarylmethane products. The use of a Weinreb amide substrate allows for facile postcoupling modification, as demonstrated by a transformation to the corresponding ketone.
