Preparation of 2,2-disubstituted and 2-monosubstituted alkenylboronic acid esters from aliphatic and aromatic ketones and aldehydes by the boron-Wittig olefination with bis[(pinacolato)boryl]methane was examined and applied on the multigram scale. The influence of the substrate steric and electronic features on the overall efficiency and stereochemical outcome of the reaction was studied. Additionally, a series of diversely functionalized (hetera)cycloalkylidenemethyl and (hetera)cycloalkyl boronic acid-derived building blocks was synthesized.

The goal for catalyst development, both homogeneous and heterogeneous, using bio-based feedstocks is designing new and robust materials for the dehydration, decarboxylation, decarbonylation, hydrogenolysis, esterification, and ketonization reactions that are required for converting these renewable, generally oxygenated feedstocks to desirable and renewable products. This chapter summarizes the work done on developing bio-based products in the last decade using the seminal US Department of Energy report on the top twelve bio-based chemicals as a starting point to assess catalyst improvement, novel process options, commercialization potential, and market penetration when possible.

22929-52-8, Name is Dihydrofuran-3(2H)-one, belongs to tetrahydrofurans compound, is a common compound. Product Details of 22929-52-8In an article, once mentioned the new application about 22929-52-8.

N-Alkylation of indoles is one of the important pathways for the construction of various biologically active indole molecules. Using ketones as N-alkylation reagent for indoles has been a great challenge not only because of the competing alkylation reaction of C-3 position but also because of the poor nucleophilicity of the nitrogen atom of indole, in addition to the steric hindrance and lower electrophilicity of the ketones. A dearomatization-rearomatization strategy has been developed for reductive cross-coupling of indoles with ketones in water. Various functional groups and other heterocyclic compounds are tolerated.

The jet-cooled fluorescence excitation spectra of the S1(n, pi*) states of tetrahydrofuran-3-one, CH2OCH2CH2C=O, and tetrahydrothiophen-3-one, CH2SCH2CH2C=O, have been recorded and analyzed. The carbonyl inversion bands, which arise from double-minimum potential energy functions in the excited states, were fit with functions of the form V=ax4-bx2 or V=cx2+d exp(-fx2). The furanone was found to have an inversion barrier in the S1(n, pi*) state of 1152 cm-1(13.8 kJ/mol) while the thiophenone has a barrier of 659 cm-1 (7.9 kJ/mol). The two molecules have their potential energy minima for the S1(n, pi*) state at carbonyl wagging angles of 26 and 20, respectively. The results here, together with previous data for several other cyclic ketones, demonstrate that the inversion barrier increases with the ring angle strain at the ketone carbon atom.
