Molecular structure effects in the asymmetric transfer hydrogenation of functionalized dihydroisoquinolines on (S,S)-[RuCl(η 6-p-cymene) TsDPEN]

The asymmetric transfer hydrogenation of five dihydroisoquinolines (DHIQs) was studied by NMR spectroscopy. The DHIQs differed by substitution with methoxy groups, which had a significant effect upon the reaction performance in terms of reaction rate and enantioselectivity. The differences are most probably related to the basicity of DHIQs.

Synthesis of Functionalized Indolines and Dihydrobenzofurans by Iron and Copper Catalyzed Aryl C-N and C-O Bond Formation

A simple and effective one-pot, two-step intramolecular aryl C-N and C-O bond forming process for the preparation of a wide range of benzo-fused heterocyclic scaffolds using iron and copper catalysis is described. Activated aryl rings were subjected to a highly regioselective, iron(III) triflimide-catalyzed iodination, followed by a copper(I)-catalyzed intramolecular N-or O-arylation step leading to indolines, dihydrobenzofurans, and six-membered analogues. The general applicability and functional group tolerance of this method were exemplified by the total synthesis of the neolignan natural product, (+)-obtusafuran. DFT calculations using Fukui functions were also performed, providing a molecular orbital rationale for the highly regioselective arene iodination process.

Design and synthesis of sulfonamidophenylethylureas as novel cardiac myosin activator

To optimize the lead urea scaffold 1 and 2 as selective cardiac myosin ATPase activator, a series of urea derivatives have been synthesized to explore its structure activity relationship. Among them N,N-dimethyl-4-(2-(3-(3-phenylpropyl)ureido)ethyl)benzenesulfonamide (13, CMA = 91.6%, FS = 17.62%; EF = 11.55%), N,N-dimethyl-4-(2-(1-methyl-3-(3-phenylpropyl)ureido)ethyl)benzene sulfonamide (40, CMA = 52.3%, FS = 38.96%; EF = 24.19%) and N,N-dimethyl-4-(2-(3-methyl-3-(3-phenylpropyl)ureido)ethyl)benzenesulfonamide (41, CMA = 47.6%, FS = 23.19%; EF = 15.47%) proved to be efficient to activate the cardiac myosin in vitro and in vivo. Further the % change in ventricular cell contractility at 5 μM of 13 (47.9 ± 3.2), 40 (45.5 ± 2.4) and 41 (63.5 ± 2.2) showed positive inotropic effect in isolated rat ventricular myocytes. The potent compounds 13, 40, 41 were highly selective for cardiac myosin over skeletal and smooth muscle myosin, thus proving them these new urea derivatives is a novel scaffold for discovery of cardiac myosin activators for the treatment of systolic heart failure.

Biocatalytic N-Acylation of Amines in Water Using an Acyltransferase from Mycobacterium smegmatis

A straightforward one-step biocatalyzed synthesis of different N-acyl amides in water was accomplished using the versatile and chemoselective acyltransferase from Mycobacterium smegmatis (MsAcT). Acetylation of primary arylalkyl amines was achieved with a range of acetyl donors in biphasic systems within 1 hour and at room temperature. Vinyl acetate was the best donor which could be employed in the N-acetylation of a large range of primary amines in excellent yields (85–99%) after just 20 minutes. Other acyl donors (including formyl-, propionyl-, and butyryl-donors) were also efficiently employed in the biocatalytic N-acylation. Finally, the biocatalyst was tested in transamidation reactions using acetamide as acetyl donor in aqueous medium, reaching yields of 60–70%. This work expands the toolbox of preparative methods for the formation of N-acyl amides, describing a biocatalytic approach easy to accomplish under mild conditions in water. (Figure presented.).

Oxalyl amide assisted palladium-catalyzed arylation of C(sp2)-H bond at the δ position

A successful protocol has been developed for δ-arylation of β-arylethamines at the ortho position under mild conditions. The newly developed methodology first presents broad substrate scope, great functional group tolerance, and good to excellent yield in the synthesis of substituted β-arylethylamines. The transformation represents a practical advantage of oxalyl amide in assistance with C-H functionalization at a remote position.

Mechanistic and structural analysis of Drosophila melanogaster arylalkylamine N-acetyltransferases

(Chemical Equation Presented). Arylalkylamine N-acetyltransferase (AANAT) catalyzes the penultimate step in the biosynthesis of melatonin and other N-acetylarylalkylamides from the corresponding arylalkylamine and acetyl-CoA. The N-acetylation of arylalkylamines is a critical step in Drosophila melanogaster for the inactivation of the bioactive amines and the sclerotization of the cuticle. Two AANAT variants (AANATA and AANATB) have been identified in D. melanogaster , in which AANATA differs from AANATB by the truncation of 35 amino acids from the N-terminus. We have expressed and purified both D. melanogaster AANAT variants (AANATA and AANATB) in Escherichia coli and used the purified enzymes to demonstrate that this N-terminal truncation does not affect the activity of the enzyme. Subsequent characterization of the kinetic and chemical mechanism of AANATA identified an ordered sequential mechanism, with acetyl-CoA binding first, followed by tyramine. We used a combination of pH-activity profiling and site-directed mutagenesis to study prospective residues believed to function in AANATA catalysis. These data led to an assignment of Glu-47 as the general base in catalysis with an apparent pKa of 7.0. Using the data generated for the kinetic mechanism, structure-function relationships, pH-rate profiles, and site-directed mutagenesis, we propose a chemical mechanism for AANATA.
