Periphery-modified crown ethers. Synthesis of bis-5,8-dimethoxy-1,4-methanonaphthalene-fused crown ethers was written by Chou, Teh-Chang;Chen, Shing-Yi;Chen, Yie-Hsung. And the article was included in Tetrahedron in 2003.Computed Properties of C11H22O5 This article mentions the following:
The easily accessible and multi-functionalized 5,8-dimethoxy-6,7-dihydroxy methyl-1,4-dihydro-1,4-methanonaphthalene (I) has been utilized as the basic building material to synthesize the sym. bis-methanonaphthalene-fused crown ethers (BMN-16-crown-4, BMN-22-crown-6, BMN-28-crown-8, and BMN-34-crown-10), that are constructed based on the connection between the α,β-bis-benzylic carbon atoms of diol I and oligoethylene glycols via two synthetic routes keyed upon the method of Williamson ether synthesis. These compounds are constructed based on the connection between the α,β,-bis-benzylic carbon atoms of diol and oligoethylene glycols via two synthetic routes keyed upon the method of Williamson ether synthesis. Crystal structures of one of the products (in syn- and anti-forms) are also reported. In the experiment, the researchers used many compounds, for example, 2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol (cas: 60221-37-6Computed Properties of C11H22O5).
2-(2-(2-((Tetrahydro-2H-pyran-2-yl)oxy)ethoxy)ethoxy)ethan-1-ol (cas: 60221-37-6) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Computed Properties of C11H22O5
