I found the field of Chemistry very interesting. Saw the article Asymmetric Synthesis of Enantioenriched 2-Aryl-2,3-Dihydrobenzofurans by a Lewis Acid Catalyzed Cyclopropanation/Intramolecular Rearrangement Sequence published in 2019.0. Category: esters-buliding-blocks, Reprint Addresses Ryu, DH (corresponding author), Sungkyunkwan Univ, Dept Chem, 300 Cheoncheon, Suwon 16419, South Korea.. The CAS is 103-25-3. Through research, I have a further understanding and discovery of Methyl 3-phenylpropionate
A cyclopropanation/intramolecular rearrangement initiated by the Michael addition of in situ generated ortho-quinone methides (o-QMs) has been developed for the enantioselective synthesis of 2-aryl-2,3-dihydrobenzofurans containing two consecutive stereogenic centers, including a quaternary carbon atom. In the presence of a chiral oxazaborolidinium ion catalyst, the reaction proceeded in excellent yields (up to 95 %) with excellent stereoselectivity (up to >99 ee, up to >20:1 d.r.).
