Photoacid-catalyzed acetalization of carbonyls with alcohols.
Saway J, Pierre AF, Badillo JJ. Saway J, et al. Org Biomol Chem. 2022 Aug 10;20(31):6188-6192. doi: 10.1039/d2ob00435f. Org Biomol Chem. 2022. PMID: 35876112
In this report, we demonstrate that visible light photoactivation of 6-bromo-2-naphthol facilitates the photoacid-catalyzed acetalization of carbonyls with alcohols. We also demonstrate that 2-naphthol when coupled to a photosensitizer provides acetals from electron …

Hydride-Abstraction-Initiated Catalytic Stereoselective Intermolecular Bond-Forming Processes.
Liu L. Liu L. Acc Chem Res. 2022 Dec 6;55(23):3537-3550. doi: 10.1021/acs.accounts.2c00638. Epub 2022 Nov 17. Acc Chem Res. 2022. PMID: 36384272
Subsequently, we developed an "acetal pool" strategy as the toolbox to regulate the stability of cationic intermediates and the compatibility of organic oxidants with a delicate asymmetric catalysis system. ...Simultaneously, we extended this strategy to the asymmetric oxi …

Catalytic asymmetric transacetalization.
Corić I, Vellalath S, List B. Corić I, et al. J Am Chem Soc. 2010 Jun 30;132(25):8536-7. doi: 10.1021/ja102753d. J Am Chem Soc. 2010. PMID: 20527773
The chiral phosphoric acid TRIP was demonstrated to be an efficient and highly enantioselective catalyst for the activation of O,O-acetals. The reaction enables the asymmetric synthesis of acetals with the acetal carbon as the only stereogenic center....

Acetal-Based Functional Epoxide Monomers: Polymerizations and Applications.
Baek J, Kim M, Park Y, Kim BS. Baek J, et al. Macromol Biosci. 2021 Nov;21(11):e2100251. doi: 10.1002/mabi.202100251. Epub 2021 Aug 8. Macromol Biosci. 2021. PMID: 34369084 Review.
In this context, many functional epoxide monomers with proper protecting groups are developed, including the acetal group as a representative example. Since the early introduction of ethoxyethyl glycidyl ether, there is significant development of acetal-based …

Degradable Glycopolyester-like Nanoparticles by Radical Ring-Opening Polymerization.
Pesenti T, Domingo-Lopez D, Gillon E, Ibrahim N, Messaoudi S, Imberty A, Nicolas J. Pesenti T, et al. Biomacromolecules. 2022 Sep 12;23(9):4015-4028. doi: 10.1021/acs.biomac.2c00851. Epub 2022 Aug 16. Biomacromolecules. 2022. PMID: 35971824
A small library of degradable polyester-like glycopolymers was successfully prepared by the combination of radical ring-opening copolymerization of 2-methylene-1,3-dioxepane as a cyclic ketene acetal (CKA) with vinyl ether (VE) derivatives and a Pd-catalyzed thiogly …
