Synthesis of N-Acyl carbamates and oxazolidinones using HClO 4-SiO2 as catalyst under solvent-free conditions

Silica supported perchloric acid catalyzes efficiently the reaction of carbamates and oxazolidinones with anhydrides in the presence of silica sulfuric acid under solvent-free conditions. All the reactions were done at room temperature and the N-acyl carbamates and oxazolidinones were obtained with high yields and purity via an easy work-up procedure.

Mechanisms, polymerization rate scaling, and oxygen inhibition with an ultra-rapid monovinyl urethane acrylate

Certain monovinyl (meth)acrylate monomers with secondary functionalities such as urethanes have been shown to exhibit extremely rapid curing rates. In this work, the polymerization mechanism, polymerization rate scaling, and relative oxygen inhibition are evaluated for an ultra-rapid butyl urethane acrylate and an analogous aliphatic urethane diacrylate. The aliphatic urethane diacrylate was found to have increased polymerization rates at higher initiation rates relative to the butyl urethane acrylate, primarily due to different termination mechanisms. Additionally, due to higher viscosity and crosslinking density, the aliphatic urethane diacrylate was found to exhibit a greater resistance to oxygen inhibition. The flux of oxygen into the aliphatic urethane diacrylate was 1/3 that of butyl urethane acrylate. Suppressed termination likely contributes to the rapid polymerization kinetics of butyl urethane acrylate.

An efficient synthesis of cyclic beta-amino acid derivatives as beta-turn mimetics

Seven-, eight-, and nine-membered cyclic beta-amino acids, precursors of platelet aggregation inhibitors, were synthesized for the first time starting from N-alkenyl amines and ethyl acrylate via ring-closing metathesis (RCM) as the key reaction. Synthesis of the corresponding enantiomerically pure beta-amino acids was also accomplished in a similar manner using Evans’ asymmetric allylation.

Generation and Cycloadditions of 4,5-Dihydrooxazole- and Oxazolidine-4-carbonitrile N-Oxides

A route to 2-phenyl-4,5-dihydrooxazole-4-carbonitrile N-oxide 7 has been developed starting from (S)-serine methyl ester and involving dehydration of the 4-nitromethyl derivative 13 using m-tolylene diisocyanate and triethylamine.Cycloaddition of the nitrile oxide to styrene afforded a 55:45 mixture of diastereoisomeric dihydroisoxazoles 21 and 22; furazan N-oxides 19 and 20 were also formed in a competing dimerisation.The analogous (R)-oxazolidine-4-carbonitrile oxide 8, also prepared from (S)-serine methyl ester, reacted similarly with styrene, oct-1-ene and diethyl fumarate to afford ca. 1:1 mixtures of adducts.The structures of the dihydrooxazole-dihydroisoxazole adduct 21 and furazan N-oxide 20 were determined by X-ray crystallography.

Insecticidal activity of novel thioureas and isothioureas

BACKGROUND: We hypothesized that the exploration of chemical space around compounds with reported insecticidal activity could be a viable strategy for discovering novel, insecticidally active areas of chemistry. RESULTS: A series of thioureas and isothioureas were prepared as part of a scaffold-hopping effort around known insecticidal compounds. Many of these compounds showed excellent activity against key sap-feeding insect pests in insecticidal bioassays. While analogs bearing monocyclic thiophene head groups showed activity against Myzus persicae (green peach aphid), analogs with diarylethane head groups were active against both M. persicae and Bemisia tabaci (sweetpotato whitefly). Despite compelling activity in these laboratory tests, these compounds showed diminished activity when applied to host plants via tracksprayer. CONCLUSIONS: The initial hypothesis that structural modification of molecules reported to have insecticidal activity would yield novel compounds that also exhibit insecticidal activity was validated. Despite excellent activity in laboratory bioassays, these new compounds failed to show compelling activity in more demanding tracksprayer tests.

Synthesis and characterization of imine-palladacycles containing imidate “pseudohalide” ligands: Efficient Suzuki-Miyaura cross-coupling precatalysts and their activation to give Pd0Ln species (L = Phosphine)

Dinuclear palladacyclic complexes [{Pd(C^N)(mu-NCO)} 2] (C^N = N-phenylbenzaldimine, Phbz) containing asymmetric imidato units (-NCO- = succinimidate (succ; 1), phthalimidate (phthal; 2), maleimidate (mal; 3), 2,3-dibromomaleimidate (2,3-diBrmal; 4), glutarimidate (glut; 5)) have been readily prepared by reaction between the di-mu-acetate precursor and cyclic imide ligands in a 1:2 molar ratio. Base treatment of the less acidic ligands 2-oxazolidone and delta-valerolactame with KOH/MeOH was required to give analogous -NCO- bridged complexes (6 and 7). Reactions of the dinuclear complexes with tertiary phosphines provide novel mononuclear N-bonded imidate derivatives of the general formula [Pd(Phbz)(imidate)(PR3)] (R = Ph (a), 4-F-C6H4 (b), 4-MeO-C6H4 (c), CH2CH2CN (d)). The application of these novel palladacyclic complexes as precatalysts for the Suzuki-Miyaura cross-coupling reactions of both aryl and benzyl bromides with phenylboronic acid has been examined. The acetate adducts [Pd(Phbz)(CH 3COO)(PR3)] (8a,c) were prepared to assess the role of imidate ligands in catalyst performance. The mononuclear imidate derivatives possess greater activity than the parent dinuclear complexes, exhibiting comparable performance in the cross-coupling of benzyl bromide with arylboronic acids to the best examples reported in the literature. The mononuclear imidate derivatives give a common Pd0Ln intermediate, as inferred by the release of the organic fragment (first reductive elimination product). Catalyst activation occurs by reaction of phenylboronic acid with the palladacycle in the absence of exogenous base (as shown by GC-MS and ESI-MS), with implications for the reliable comparison of catalyst performance across a series of related precatalysts (e.g., how catalyst/reagents are mixed and what is their order of addition). The single-crystal X-ray structures of compounds 4, 7, 1d, 3c, and 8a have been determined.
