Enantioselective Synthesis of P-Stereogenic Compounds

Abstract

Methods for enantioselective synthesis of P-stereogenic compounds from non-optically active substrates are reviewed. Two stategies can be classified according to the substrates and mechanisms of their reactions, which include enantioselective desymmetrisations and chemical resolutions.

Nanomaterial‐enabled Rapid Detection of Water Contaminants

“…Fluorescence detection of heavy metal ions was another important method for monitoring water quality. [62][63][64] In this type of sensor, artifi cial receptors that exhibit changes in their fl uorescence properties upon binding to heavy metal ions are recognized as powerful detection tools due to their high sensitivity and selectivity. [ 65 ] In particular, quantum dots (QDs) [ 66,67 ] can generate narrow, size-tunable, and symmetric emission spectra, which makes them excellent donors for fl uorescence resonance energy transfer (FRET) or nanometal surface energy transfer (NSET) sensors [ 68 ] and offers signifi cant advantages over organic dyes as optical labels for chemo/biosensing.…”

Encapsulating Sb/MoS2 Into Carbon Nanofibers Via Electrospinning Towards Enhanced Sodium Storage

“…To this end, many efforts have been made to develop high‐performance anode materials, including intercalation‐type hard carbon/oxides (e. g., TiO 2 ), [8–10] hybrid‐type metal chalcogenides (e. g., MoS 2 ), [11] conversion‐type metal oxides/chalcogenides (e. g., CoSe 2 ), [12] alloy‐type metals/metal oxides (e. g., Sb, SnO 2 ) [9,13,14] . Among these candidates, MoS 2 and metallic Sb have been identified as promising anode materials for SIBs [9,11,13] .…”

Among these candidates, MoS 2 and metallic Sb have been identified as promising anode materials for SIBs [9,11,13] . As a typical graphite‐like layered transition metal dichalcogenide, MoS 2 possesses large intrinsic interlayer spacing (0.62 nm), which is suitable for intercalation and de‐intercalation of Na + ions, leading to a high theoretical specific capacity of 670 mAh g −1 [15] .…”
