I found the field of Chemistry very interesting. Saw the article N-Heterocyclic carbene-catalyzed beta-addition of enals to 3-alkylenyloxindoles: synthesis of oxindoles with all-carbon quaternary stereocenters published in 2019.0. SDS of cas: 103-25-3, Reprint Addresses Ye, S (corresponding author), Chinese Acad Sci, Beijing Natl Lab Mol Sci, CAS Key Lab Mol Recognit & Funct, CAS Res Educ Ctr Excellence Mol Sci,Inst Chem, Beijing 100190, Peoples R China.; Ye, S (corresponding author), Univ Chinese Acad Sci, Beijing 100049, Peoples R China.. The CAS is 103-25-3. Through research, I have a further understanding and discovery of Methyl 3-phenylpropionate
The N-heterocyclic carbene-catalyzed beta-addition of enals to 3-alkylenyloxindoles was developed. All of the beta-aryl, beta-alkenyl and beta-alkyl enals worked well for the reaction to give the corresponding 3,3-disubstituted oxindoles bearing contiguous all-carbon quaternary and tertiary stereocenters in good yields with moderate to high diastereoselectivities and excellent enantioselectivities.
SDS of cas: 103-25-3. About Methyl 3-phenylpropionate, If you have any questions, you can contact Zhang, CL; Han, YF; Ye, S or concate me.
