A highly enantioselective (S) diphenylpyrrolinol silyl ether promoted tandem Michael−aldol reaction of α,β-unsaturated aldehydes with 2-mercaptobenzaldehydes has been developed. The method affords one-pot access to chiral and synthetically useful thiochromenes in high yields enantioselectivities from readily available compounds.
For drug delivery in cancer therapy, various stimuli-responsive hydrogel-based micro-devices have been studied with great interest. Here, we present a new concept for hybrid actuated soft microrobot targeted delivery. The proposed consists of hydrogel bilayer structure 2-hydroxyethyl methacrylate (PHEMA) and poly (ethylene glycol) acrylate (PEGDA) iron (II, III) oxide particles (Fe3O4). PHEMA layer as pH-responsive gel is used trapping unfolding motion the pH-varying solution,...
Just can't get enough: The highly versatile pyrrolidine sulfonamide organocatalyst 1, which has been used in α-aminoxylation and Mannich-type reactions, also mediates diastereo- enantioselective Michael addition reactions of aldehydes ketones to nitroolefins (see scheme).
Quantum dots (QDs)-based molecularly imprinted polymer (MIP) composite nanospheres were successfully prepared via a facile and versatile ultrasonication-assisted encapsulation method. Unlike the hydrogen-bond-based MIPs, these so-prepared QDs-MIP nanospheres, relying on interaction including van der Waals forces hydrophobic forces, demonstrated excellent selectivity in aqueous media. Their small particle sizes carboxyl-enriched matrixes give rise to their good dispersibility stability...

The method is simple and facile, in which mesostructured synthesized Stöber solution can spontaneously transform to structure when they are incubated water. formation does not require any sacrificial templates, emulsion droplets, or surface protective agents. obtained possess controllable diameter, tunable shell thickness, high specific area,...
Imitating the natural photosynthesis to synthesize hydrocarbon fuels represents a viable strategy for solar-to-chemical energy conversion, where utilizing low-energy photons, especially near-infrared has been ultimate yet challenging aim further improving conversion efficiency. Plasmonic metals have proven their ability in absorbing however, it remains an obstacle effectively coupling this into reactant molecules. Here we report broadband plasmon-induced CO2 reduction reaction with water,...
Highly enantio- and diastereoselective tandem Michael−aldol reactions, efficiently catalyzed by a cinchona alkaloid thiourea via synergistic noncovalent hydrogen-bonding activation of both the Michael donor acceptor, have been developed. The process affords powerful means for construction versatile chiral thiochromanes with formation three stereogenic centers in one-pot synthesis from simple achiral compounds.

Fluorous (S) pyrrolidine sulfonamide serves as an efficient promoter for highly enantioselective aldol reactions of ketones and aldehydes with aromatic on water. A notable feature the organocatalyst is that it can be recovered from reaction mixtures by simple fluorous solid-phase extraction subsequently reused (up to seven cycles) without a significant loss catalytic activity stereoselectivity.

Although many studies have contributed to progressive nanorobot system anticancer drug these systems still face some critical limitations, such as potentially toxic materials nanorobots, unreasonable sizes passive targeting, lack several essential functions delivery sensing, active controlling release, sufficient loading...
Targeted drug delivery using a microrobot is promising technique capable of overcoming the limitations conventional chemotherapy that relies on body circulation. However, most studies microrobots used for have only demonstrated simple mobility rather than precise targeting methods and prove possibility biodegradation implanted after delivery.

Abstract The relatively short‐lived excited states, such as the nascent electron–hole pairs (excitons) and shallow trapping in semiconductor‐based photocatalysts produce an exceptionally high charge carrier recombination rate, dominating a low solar‐to‐fuel performance. Here, π‐conjugated in‐plane heterostructure between graphitic carbon nitride (g‐CN) rings (C ) (labeling g‐CN/C is effectively synthesized from thermolysis of melamine–citric acid aggregates via microwave‐assisted heating...
Semiconductor-based heterostructures have exhibited great promise as a photocatalyst to convert solar energy into sustainable chemical fuels, however, their solar-to-fuel efficiency is largely restricted by insufficient interfacial charge separation and limited catalytically active sites. Here the integration of high-efficiency sufficient single-atom metal sites in 2D van der Waals (vdW) heterostructure between ultrathin polymeric carbon nitride (p-CN) Ni-containing Salphen-based covalent...
