SDS of cas: 99-04-7. I found the field of Chemistry very interesting. Saw the article Chiral Bicyclic Imidazole-Catalyzed Acylative Dynamic Kinetic Resolution for the Synthesis of Chiral Phthalidyl Esters published in 2021, Reprint Addresses Zhang, WB (corresponding author), Shanghai Jiao Tong Univ, Shanghai Key Lab Mol Engn Chiral Drugs, Sch Pharm, 800 Dongchuan Rd, Shanghai 200240, Peoples R China.; Zhang, WB (corresponding author), Shanghai Jiao Tong Univ, Sch Chem & Chem Engn, Frontiers Sci Ctr Transformat Mol, 800 Dongchuan Rd, Shanghai 200240, Peoples R China.. The CAS is 99-04-7. Through research, I have a further understanding and discovery of 3-Methylbenzoic acid.
Utilizing a chiral bicyclic imidazole organocatalyst and adopting a continuous injection process, an alternative route has been developed for the efficient synthesis of chiral phthalidyl ester prodrugs via dynamic kinetic resolution of 3-hydroxyphthalides through enantioselective acylation (up to 99 % ee). The computational studies suggest a general base catalytic mechanism differing from the widely accepted nucleophilic catalytic mechanism. The structure analysis of the key transition states shows that the CH-pi interactions and not the previously considered cation/pi-pi interactions between the catalyst and substrate is the dominant factor giving rise to the observed stereocontrol.
