Preparations and reactions of acylated and partially acylated glycosyl fluorides
Carbohydrate Research, 1993Abstract Partial acylation of glycosyl fluorides in the galacto (2 and 3) and gluco series (8–10) is readily achieved. Attempts to further alkylate these acyl derivatives failed. Treatment of 2 with Lewis acid, however, provided a facile route to the 1,4-anhydro derivative 5 . Lewis acid-mediated glycosylation of 2-acetamido-3,4,6-tri- O -

Acyl Fluorides in Late‐Transition‐Metal Catalysis
Angewandte Chemie International Edition, 2019AbstractIn this Review, we summarize the current state of the art in late‐transition‐metal‐catalyzed reactions of acyl fluorides, covering both their synthesis and further transformations. In organic reactions, the relationship between stability and reactivity of the starting substrates is usually characterized by a trade‐off.

Copper‐Catalyzed Asymmetric Acylboration of 1,3‐Butadienylboronate with Acyl Fluorides
Angewandte Chemie International Edition, 2023AbstractWe report herein a Cu‐catalyzed regio‐, diastereo‐ and enantioselective acylboration of 1,3‐butadienylboronate with acyl fluorides. Under the developed conditions, the reactions provide (Z)‐β,γ‐unsaturated ketones bearing an α‐tertiary stereocenter with high Z‐selectivity and excellent enantioselectivities.

Decarboxylative Cross-Coupling of Acyl Fluorides with Potassium Perfluorobenzoates
Organic Letters, 2020We report the transition metal-free decarboxylative cross-coupling reactions of acyl fluorides with potassium perfluorobenzoates. Compared with traditional transition metal-catalyzed cross-couplings, this protocol presents an extremely environmentally benign pathway to afford unsymmetrical diaryl ketones.
