A mild and efficient protocol for O-arylation of alcs. and phenols by triarylsulfonium triflates was developed under transition-metal-free conditions. Various alcs., including primary, secondary and tertiary and phenols bearing either electron-donating or electron-withdrawing groups on the aryl rings were smoothly converted to form the corresponding aromatic ethers e.g., I in moderate to excellent yields. The reactions were conducted at 50 or 80 °C for 24 h in the presence of a certain base and showed good functional group tolerance. The base-mediated arylation with asym. triarylsulfonium salts could selectively transfer the aryl groups of sulfoniums to alcs., depending on their inherent electronic nature. The mechanistic studies revealed that the reaction might proceed through the nucleophilic attack of the in situ formed alkoxy or phenoxy anions at the aromatic carbon atoms of the C-S bonds of triarylsulfonium cations to furnish the target products. In the experiment, the researchers used ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6Recommanded Product: 20880-92-6)
((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol(cas: 20880-92-6) is a useful reactant for examining the effectiveness of sulfamate and sulfamide groups for the inhibition of carbonic anhydrase-II (CA-II). And it is used as chiral auxiliaries in Michael and Aldol addition reactions.Recommanded Product: 20880-92-6
