I found the field of Chemistry very interesting. Saw the article Catalytic enantioselective allene-anhydride approach to beta,gamma-unsaturated enones bearing an alpha-all-carbon-quarternary center published in 2020. Safety of Benzoic anhydride, Reprint Addresses Qian, H; Ma, SM (corresponding author), Fudan Univ, Res Ctr Mol Recognit & Synth, Dept Chem, 220 Handan Lu, Shanghai 200433, Peoples R China.; Zhang, X; Ma, SM (corresponding author), Chinese Acad Sci, Shanghai Inst Organ Chem, State Key Lab Organometall Chem, 345 Lingling Lu, Shanghai 200032, Peoples R China.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
A protocol of highly regio- and enantioselective copper-catalyzed hydroacylation of the non-terminal CC bond in 1,1-disubstituted terminal allenes with anhydrides has been developed. Both aromatic and aliphatic carboxylic anhydrides are applicable to the efficient construction of all carbon quarternary centers connected with a versatile C-C bond and a useful ketone functionality. The synthetic potentials of the enantioenriched products have also been demonstrated. Density functional theory (DFT) calculations were performed to explain the steric outcome of the products: the hydroacylation proceeds through a six-membered transition state and the ligand-substrate steric interactions account for the observed enantioselectivity although the chiral ligand is far away from the to-be-genetated chiral center.
Safety of Benzoic anhydride. Bye, fridends, I hope you can learn more about C14H10O3, If you have any questions, you can browse other blog as well. See you lster.
