用途有機合成原料。
使用2-(2-Bromoethyl)-1,3-dioxolane is used as a pharmaceutical intermediate, dioxolanes, acetals, ketals, building blocks, chemical synthesis, organic building blocks and oxygen compounds. 1,1-(Ethylenedioxy)-3-bromopropane is used in the synthesis of EGFR inhibitors. Also used in the synthesis of orally active agents of cancer and cell proliferation with quinoline substructures. It is also used as flavouring agent.
一般的な説明Copper-catalyzed borylation of 2-(2-bromoethyl)-1,3-dioxolane with bis(pinacolato)diboron followed by treatment with potassium bifluoride affords the key organotrifluoroborate reagent.
純化方法Dissolve it in pentane, wash with 5% aqueous NaHCO3, dry (Na2SO4), and evaporate. Distil the residue. [NMR: Büchi & Wüest J Org Chem 34 1122 1969, Kriesat & Gisvold J Pharm Sci 60 1250 1971, Beilstein 19/1 V 69.]
