A straightforward synthesis of the tetrasaccharide repeating unit of the O-antigen of Escherichia coli O16 has been achieved following a sequential glycosylation strategy. A minimum number of steps was used for the synthesis of the target compound involving a one-pot glycosylation and a protecting group manipulation. All intermediate reactions afford their products in high yield, and the glycos...

We report a flexible de novo synthesis of phenolic dihydroxanthene fluorophores. The synthesis relies on a one-pot formation of an aldehyde intermediate which can be diversified in 60-70% overall yield, providing an efficient access to this family of near-infrared emitting fluorophores.

An effective one-pot synthesis of quinolines bearing diverse C3-piperazinyl functions was developed by using a modified Friedländer's protocol. The method not only enables the synthesis of our early reported c-Met inhibitor on a large scale, but also provides a way to generate novel multi-substituted quinolines for further structure-activity relationship (SAR) study.

In this work, the efficiency, generality and applicability of new Bronsted acidic ionic liquid (BAIL) 1-methyl-3-(2-(sulfooxy)ethyl)-1H-imidazol-3-ium chloride {[Msei]Cl} as heterogeneous and green catalyst for organic transformations are studied. Herein, the following one-pot multi-component reactions in the presence of [Msei]Cl are investigated: (i) the synthesis of quinoxaline derivatives fr...

A combinatorial ionic-liquid-supported "catch-and-release" strategy for oligosaccharide synthesis (combi-ICROS) is reported. A series of β-(1→6) glucan di-, tri- and tetra-saccharides were synthesized in one pot to showcase the versatility of the strategy.
