Abstract
Lipopolysaccharides from the commensal gut-associated microbiota are interesting biomolecules for the treatment of various inflammatory diseases. Different from pathogenic lipopolysaccharides, commensal lipopolysaccharides have distinct chemical structures and mediate beneficial homeostasis with the immune system of the host. However, the accessibility issues of homogenous and pure commensal lipopolysaccharides hampered the in-depth studies of their functions. In this concept article, we highlight the recent synthesis of lipopolysaccharides from gut-associated lymphoid-tissue-resident Alcaligenes faecalis and Bacteroides vulgatus, which hopes to inspire the more efforts devoting to these fantastic biomolecules.

Abstract
![]()
The stereoselective
introduction of glycosidic bonds is of paramount
importance to oligosaccharide synthesis. Among the various chemical
strategies to steer stereoselectivity, participation by either neighboring
or distal acyl groups is used particularly often. Recently, the use
of the 2,2-dimethyl-2-(ortho-nitrophenyl)acetyl (DMNPA)
protection group was shown to offer enhanced stereoselective steering
compared to other acyl groups. Here, we investigate the origin of
the stereoselectivity induced by the DMNPA group through systematic
glycosylation reactions and infrared ion spectroscopy (IRIS) combined
with techniques such as isotopic labeling of the anomeric center and
isomer population analysis. Our study indicates that the origin of
the DMNPA stereoselectivity does not lie in the direct participation
of the nitro moiety but in the formation of a dioxolenium ion that
is strongly stabilized by the nitro group.

Abstract
The anomeric configuration can greatly affect the biological functions and activities of carbohydrates. Herein, we report that N-phenyltrifluoroacetimidoyl (PTFAI), a well-known leaving group for catalytic glycosylation, can act as a stereodirecting group for the challenging 1,2-cis α-glycosylation. Utilizing rapidly accessible 1,6-di-OPTFAI glycosyl donors, TMSOTf-catalyzed glycosylation occurred with excellent α-selectivity and broad substrate scope, and the remaining 6-OPTFAI group can be cleaved chemoselectively. The remote participation of 6-OPTFAI is supported by the first characterization of the crucial 1,6-bridged bicyclic oxazepinium ion intermediates by low-temperature NMR spectroscopy. These cations were found to be relatively stable and mainly responsible for the present stereoselectivities. Further application is highlighted in glycosylation reactions toward trisaccharide heparins as well as the convergent synthesis of chacotriose derivatives using a bulky 2,4-di-O-glycosylated donor.
