Combining bio- and chemocatalysts for chemoenzymatic reaction sequences is of high interest to organic chemistry. In this study, we combined a ring-closing metathesis reaction conducted by a Grubbs? catalyst and a subsequent enzymatic ester hydrolysis reaction conducted by pig liver esterase within a two-step one-pot process. We addressed sustainability by encapsulating both catalysts in biopolymer-based hydrogels derived from renewable resources to allow straightforward recycling and using aqueous media for the reactions. When we investigated the approaches of either conducting the reaction sequence in the same solvent for both reactions or using different preferred solvents for each reaction, the enzyme activity turned out to be enhanced when encapsulating the enzyme, thus shielding it from the Grubbs? catalyst. In terms of recycling, the encapsulated catalysts demonstrated promising performance with >80 % conversion for seven runs.

Macrocyclic natural products have been recognized and utilized as new platforms for designing drugs in pharmaceutical research because the constrained three-dimensional shapes and the large surface areas of these complex structures enable selective binding to conventionally undruggable targets. Since natural products are not necessarily ideal for medicinal use, structural optimization is required to obtain superior drug candidates. However, the modifications to macrocyclic natural products that will afford the best pharmacological characteristics cannot be known a priori. Therefore, this optimization procedure requires the exploration of a vast array of natural product analogues to identify new compounds with more desirable properties. To fully explore the chemical space around complex macrocyclic natural products, the construction of a large number of analogues is required. In this review, we provide an overview of the efficient synthetic construction of the analogues of macrocyclic natural products and the evaluation of their biological activities. The examples of the comprehensive structure-activity relationship (SAR) studies depicted herein led to the discoveries of biologically useful analogues. These studies illustrate the importance of designing building blocks and coupling strategies to synthesize a variety of natural product based analogues.

By natural product inspired diversity-oriented synthesis, we had developed a new class of selective antagonist, IKM-159, for the AMPA receptor. Here, we report syntheses of IKM-159 and skeletally diverse five analogues in racemic forms, two of which are heterotricycles and the other three compounds are truncated analogues, to study the structure-activity relationships. The key reactions are two domino reactions including Ugi/Diels-Alder reaction and domino metathesis reaction. An exceptionally high level of regiocontrol in the cross metathesis reaction is also reported. Georg Thieme Verlag Stuttgart New York.

Efficient trans-hydroarylation of alkynes by simple arenes has been realized regio- and stereoselectively at room temperature in the presence of Pd(II) or Pt(II) catalysts and a mixed solvent containing trifluoroacetic acid (TFA). Various arenes undergo trans-hydroarylation selectively across terminal and internal C – C triple bonds – including those conjugated to CHO, COMe, CO2H, and CO2Et groups, affording kinetically controlled cis-arylalkenes predominantly in most cases, especially, in good yields for electron-rich arenes and activated alkynes. The formation of arene/alkyne 1/2 or 2/1 adducts as side products is dependent on the arenes’ and alkynes’ substituents, which can be suppressed in some cases by changing the catalyst, catalyst concentration, and reaction time. The Pt(II) system, PtCl2/2AgOAc/TFA, shows lower catalytic activity than Pd(OAc)2/TFA, but higher selectivity, giving higher yields of adducts at the same conversion. On the basis of several isotope experiments and control reactions, a possible mechanism involving electrophilic metalation of aromatic C – H bonds by in-situ-generated cationic Pd(II) and Pt(II) species leading to intermolecular trans-arylpalladation to alkynes has been discussed.

Reactions between HRuCl(PPh3)3 and 1,3- or 1,5-cyclooctadiene yield the 1,2-dihydropentalenyl complex (eta5-C8H9)Ru(PPh3) 2Cl through a series of steps including olefin insertion and electrocyclization. The reaction is accompanied by the loss of two equivalents of hydrogen. The product crystallizes in the monoclinic space group P1? (No. 2). (eta5-C8 H9)Ru(PPh3)2Cl catalyzes the dimerization of phenylacetylene to a ?2:1 mixture of Z: E 1,4-diphenyl-1-buten-3-yne. Comparison of the catalytic activity of (eta5-C8H9)Ru(PPh3) 2Cl with (eta5-C5H5) Ru(PPh3)2Cl, (eta5-C5 Me5)Ru(PPh3)H3 and {eta5 -HB(pz)3}Ru(PPh3)2Cl suggests that the more electron-rich eta5 ligands favor formation of the Z isomer.

Carbonyl-containing Ru and Fe heterobimetallic complexes were prepared and tested as electrocatalysts for the oxidation of methanol and ethanol. GC analysis of the electrolyte solution during bulk electrolysis indicated that CpRu(CO) (mu-I) (mu-dppm) PtI2 (1), CpFe(CO) (mu-I) (mu-dppm) -PtI2 (2), and CpRu(CO) (mu-I) (mu-dppm) PdI2 (3) were catalysts for the electrooxidation of methanol and ethanol, while CpFe(CO) (mu-I) (mu-dppm) -PdI2 (4), CpRu(CO) I(mu-dppm) AuI (5), and CpFe(CO) I(mu-dppm) AuI (6) did not function as catalysts. The oxidation of methanol resulted in two-and four-electron oxidation to formaldehyde and formic acid, respectively, followed by condensation with unreacted methanol to yield dimethoxymethane and methyl formate as the observed products. The oxidation of ethanol afforded 1, 1 – diethoxyethane as a result of two-electron oxidation to acetaldehyde and condensation with excess ethanol. FTIR analysis of the headspace gases during the electrochemical oxidation of methanol indicated formation of CO2. Isotopic labeling experiments demonstrated that the CO2 resulted from oxidation of the CO ligand instead of complete oxidation of CH3OH.

The reactions of PhSe-, PhS- and Se2- with N-{2-(chloroethyl)}pyrrolidine result in N-{2-(phenylseleno)ethyl}pyrrolidine (L1), N-{2-(phenylthio)ethyl}pyrrolidine (L2), and bis{2-pyrrolidene-N-yl)ethyl selenide (L3), respectively, which have been explored as ligands. The complexes [PdCl2(L1/L2)] (1/7), [PtCl2(L1/L2)] (2/8), [RuCl(eta6-C6H6)(L1/L2)][PF6] (3/9), [RuCl(eta6-p-cymene)(L1/L2)][PF6] (4/10), [RuCl(eta6-p-cymene)(NH3)2][PF6] (5) and [Ru(eta6-p-cymene)(L1)(CH3CN)][PF6]2·CH3CN (6) have been synthesized. The L1-L3 and complexes were found to give characteristic NMR (Proton, Carbon-13 and Se-77). The crystal structures of complexes 1, 3-6, 9 and 10 have been solved. The Pd-Se and Ru-Se bond lengths have been found to be 2.353(2) and 2.480(11)/2.4918(9)/2.4770(5) A?, respectively. The complexes 1 and 7 have been explored for catalytic Heck and Suzuki-Miyaura coupling reactions. The value of TON has been found up to 85 000 with the advantage of catalyst’s stability under ambient conditions. The efficiency of 1 is marginally better than 7. The Ru-complexes 3 and 9 are good for catalytic oxidation of primary and secondary alcohols in CH2Cl2 in the presence of N-methylmorpholine-N-oxide (NMO). The TON value varies between 8.0 × 104 and 9.7 × 104 for this oxidation. The 3 is somewhat more efficient catalyst than 9.
