I found the field of Chemistry very interesting. Saw the article A Unified Synthetic Approach to Optically Pure Curvularin-Type Metabolites published in 2019.0. Name: 4-Nitrobenzoic acid, Reprint Addresses Qi, N; Guo, J; He, Y (corresponding author), Chongqing Univ, Sch Pharmaceut Sci, Chongqing Key Lab Nat Prod Synth & Drug Res, Chongqing 401331, Peoples R China.; Qi, N (corresponding author), Chongqing Univ, Coll Bioengn, Biomed & Hlth Engn Lab, Chongqing 401331, Peoples R China.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
A unified and concise approach to the synthesis of nine curvularin-type metabolites and two analogues has been developed with few steps and high yields. Among them, sumalactones A-D were synthesized for the first time. The key steps in this approach included esterification, Friedel-Crafts acylation, and ring-closing metathesis (or cross metathesis).
