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 …

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....

TFA-Promoted Intermolecular Friedel-Crafts Alkylation of Arenes with 2,2,2-Trifluoroethylaryl Sulfoxides.
Deng Z, Qiu LY, Pan W, Qian B, Chen J, Zhang H, Chen QY, Cao W, Tang XJ. Deng Z, et al. Chem Asian J. 2022 Jul 15;17(14):e202200190. doi: 10.1002/asia.202200190. Epub 2022 Jun 10. Chem Asian J. 2022. PMID: 35644874
The classical Pummerer rearrangement of 2,2,2-trifluoroethylaryl sulfoxide with trifluoracetic anhydride (TFAA) affords the S,O-acetal efficiently. In the presence of trifluoracetic acid (TFA) as the co-solvent, the S,O-acetal can regenerate reactive thionium interm …

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 monome …
