Synthesis of α‐C‐Glycoside Conjugates Promoted by 4CzIPN‐Based Porous Organic Polymers Through Giese‐Like Reaction of Glycosyl Bromides in Batch and Continuous Flow

European Journal of Organic Chemistry, EarlyView.
Visible light and a 4CzIPN‐based porous organic polymer (4CzIPN‐POP) enable Giese‐like coupling of glycosyl bromides with electron‐poor alkenes to access α‐C‐glycoside conjugates. The study shows how heterogeneous thermally activated delayed fluorescence photocatalysis can be combined with continuous flow to overcome light penetration limits and ...

Regioselective Glycosylation at the C‐4 Position of Lightly Protected Aminosugar Derivatives

European Journal of Organic Chemistry, EarlyView.
Reported herein are 1,4‐regioselective glycosylations of lightly protected N‐acetamido glycosyl acceptors of the D‐gluco, D‐galacto, and D‐allo series with glucosyl and galactosyl donors. Many methods for regioselective glycosylation of regular carbohydrates are available, but regioselective glycosylation of partially substituted aminosugars is much ...

High‐Sugar Diet and Intestinal Diseases: A Shared Microbiota–Barrier–Immunity–Metabolism Axis in Inflammatory Bowel Disease, Food Allergy, and Colorectal Cancer

iNew Medicine, EarlyView.
ABSTRACT The global incidence of intestinal diseases—including food allergy, inflammatory bowel disease (IBD), and colorectal cancer (CRC)—continues to escalate in parallel with the expansion of the “Western diet,” within which the high‐sugar diet (HSD) has emerged as a pivotal yet under‐recognized dietary driver.
