A highly enantioselective alpha-ketol rearrangement has been developed. In the presence of a chiral Cu-bisoxazoline complex, achiral beta-hydroxy-alpha-dicarbonyls were isomerized to chiral alpha-hydroxy-beta-dicarbonyls and their bicyclic derivatives in excellent yields and enantioselectivities. Enantioenriched 2-acyl-2-hydroxy cyclohexan-1-ones, dihydroxyhexahydrobenzofuranones, and dihydroxyhexahydro-cycloheptafuranones, with up to three stereocenters, were readily prepared from achiral starting materials in one operation. The reaction is applicable to the desymmetrization of meso substrates and kinetic resolution of racemic alcohols.

The electrochemically induced tandem reaction of aldehydes and two equivalents of kojic acid has been carried out in alcohols in an undivided cell in the presence of sodium halides. It led to the selective formation of substituted arylbis[3-hydroxy-6-(hydroxymethyl)-4-oxo-4H-pyran-2-yl]methanes in 71-98% yields and with 240-330% current efficiency. This new electrocatalytic process provides green, useful and efficient way to two kojic acid fragments separated by C-aryl-substituted spacer, which are promising compounds for different biomedical applications.

A nickel-catalyzed reductive coupling between acid fluorides and vinyl triflates has been described. This method provides an efficient access to various enones and avoids the requirement for acyl or vinyl metallic reagents in the conventional approaches. The reaction proceeds with a broad range of acid fluorides and cyclic vinyl triflates, tolerating several functional groups. The utility of this synthetic method has been demonstrated by the late-stage modification of pharmaceuticals and biologically active natural compounds.

The extensively developed ene-type enantioselective cycloisomerization of classical 1,n-enynes provides an efficient approach to chiral cyclic 1,4-dienes. In contrast, the catalytic asymmetric heteroarenyne (heteroarene-alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH-catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne-tethered indole substrates (formal 1,5- and 1,6-enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives bearing quaternary stereocenters and exocyclic C=C bonds are afforded in moderate to excellent yields and excellent enantioselectivities (up to 98 % ee). The classical ene-type enantioselective 1,5-enyne cycloisomerization of N-vinylpropiolamides is also developed to afford chiral 2-pyrrolones in good to excellent ee values.

Stereochemistry of direct conversion of polyamides to hydroxyesters was investigated using model compounds. Optically active secondary-alkyl amines underwent the conversion to corresponding secondary alcohols in moderate yields by treatment with supercritical methanol in the presence of glycolic acid. The reaction progressed through almost completely stereochemical inversion to give secondary alcohols in high yields. Thus, the substitution reaction of the amino group to hydroxyl group progresses through S(N)2 type transition state accompanying with stereoinversion. (C) 2018 Published by Elsevier Ltd.

Axially chiral phenols are attractive targets in organic synthesis. This motif is central to many natural products and widely used as precursors to, or directly, as chiral ligands and catalysts. Despite their utility few simple catalytic methods are available for their synthesis in high enantiopurity. Herein the atropselective acylation of a range of symmetric biaryl diols is investigated using isothiourea catalysis. Studies on a model biaryl diol substrate shows that the high product er observed in the process is a result of two successive enantioselective reactions consisting of an initial enantioselective desymmetrization coupled with a second chiroablative kinetic resolution. Extension of this process to a range of substrates, including a challenging tetraorthosubstituted biaryl diol, led to highly enantioenriched products (14 examples, up to 98:2 er), with either HyperB(TM) or B-TM identified as the optimal catalyst depending upon the substitution pattern within the substrate. Computation has been used to understand the factors that lead to high enantiocontrol in this process, with maintenance of planarity to maximize a 1,5-S…O interaction within the key acyl ammonium intermediate identified as the major feature that determines atropselective acylation and thus product enantioselectivity.

Solar-driven water vaporization is considered one of the most sustainable technologies to solve water scarcity. However, the advanced design solar absorber system is still required for highly efficient steam generation. Here we develop a novel system for water evaporation through assembly of carbon dots within microchannels of processed wood. Not only is a dual-layer structure including of heat barrier and water transport channel formed, but also the modulation of carbon dot energy structures in favor of photothermal conversion is realized synchronously. This system exhibits higher water evaporation rate and energy efficiency for solar to steam generation than other black photothermal sheets (e.g. carbon nanotube, graphene, graphene oxide). On the one hand, the constructed size-dependent vaporization enthalpy theory shows that the micropores are beneficial to reduce vaporization enthalpy of water. On the other hand, the presented direct evidences for the roles of oxidation functional groups in solar thermal evaporation demonstrate that hydroxyl groups can improve solar-to-heat efficiency. Therefore, tailoring pore sizes and surface functional groups could be an efficient method for solar-to-vapor systems. (C) 2019 Elsevier Ltd. All rights reserved.
