Abstract Described is a tetrabutylammonium fluoride‐mediated hydroxyalkylation reaction of phenols with cyclic carbonates. This operationally simple method enables the synthesis variety aryl β‐hydroxyethyl ethers in good to excellent yields very small amount catalyst loading (0.1–1 mol%). Of particular note efficient conversion aromatic diols and phloroglucinol corresponding bis‐ tris‐hydroxyethylated products. To further showcase versatility this protocol, guaifenesin was prepared single...
Abstract Described is a deprotonative α-arylation reaction of Meyers’s chiral bicyclic lactams (MCBLs) under palladium catalysis, and substrate-dependent post-transformation. When the bridgehead carbon MCBLs substituted with methyl or an ethyl group, initial arylation product undergoes further rearrangement to give conjugated framework. On other hand, substrates bearing isopropyl aryl group are converted into corresponding exo-arylation products. Preliminary studies indicated that pathway...
Abstract Crinine and vittatine (the antipode of crinine) have long been, remain, an inspiration for the development reaction methods since their isolation in 1950s. In particular, all‐carbon quaternary stereocenter embedded these targets has fuelled creativity innovating strategies tactics synthesis. This review provides overview research endeavors toward assembling unique carboskeleton title alkaloids.
A set of cascade unsymmetrical diarylation reactions were developed taking advantage the differentiated reactivity aryl bromides and chlorides under palladium catalysis.
Atmospheric particulate matters (PMs) were measured in an industry-intensive region central Taiwan order to investigate the characteristics and possible sources of PMs. The samplings simultaneously conducted using a 10- 3-stage Micro Orifice Uniform Deposit Impactor (MOUDI) from 2017 2018. In this study, PMs evaluated by measuring mass concentration analyzing water-soluble ions metallic elements, as well dioxins. Additionally, principal component analysis (PCA) was used identify potential...
Abstract Non-road vehicles equipped with diesel engine could emit air pollutants. This study measured particulate matters (PM) and gaseous pollutants of the exhaust non-road (excavator, bulldozers) during idling operating. The concentrations TPM, PM 10 2.5 were 14-251, 12-181 10-163 mg/Nm 3 , respectively, for three on-road vehicles. occupy 60-70％ while 80-90％ . calculated emission factors 0.64 - 0.94, 0.53 0.79 0.32 -0.49 g/bhp-hr respectively. Metallic elements analyzed in order to...
Abstract Described is a formal synthesis of racemic schulzeines B and C that intercepts intermediates developed by Gurjar co‐workers. The synthetic sequence features an annulative coupling ketimine acrylic acid enabling the construction benzoquinolizidine nucleus in highly convergent manner. We also examined continuous‐flow version thermal aza‐annulation, which proved less practical as compared to batch processes.
