In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Base- and Catalyst-Induced Orthogonal Site Selectivities in Acylation of Amphiphilic Diols, published in 2020-05-15, which mentions a compound: 17696-11-6, Name is 8-Bromooctanoic acid, Molecular C8H15BrO2, SDS of cas: 17696-11-6.
Seeking to selectively functionalize natural and synthetic amphiphiles, we explored acylation of model amphiphilic diols. The use of a nucleophilic catalyst enabled a remarkable shift of the site selectivity from the polar site, preferred in background noncatalyzed or base-promoted reactions, to the apolar site. This tendency was significantly enhanced for organocatalysts comprising an imidazole active site surrounded by long/branched tails. An explanation of these orthogonal modes of selectivity is supported by competitive experiments with monoalc. substrates.
Although many compounds look similar to this compound(17696-11-6)SDS of cas: 17696-11-6, numerous studies have shown that this compound(SMILES:O=C(O)CCCCCCCBr), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
