I found the field of Chemistry very interesting. Saw the article Neighboring Carbonyl Group Assisted Oxyacetoxylation of Propargylic Carboxylates with Retention of Chirality under Metal Free Condition published in 2019. Recommanded Product: 93-97-0, Reprint Addresses Pradhan, TR; Mohapatra, DK (corresponding author), CSIR Indian Inst Chem Technol, Dept Organ Synth & Proc Chem, Hyderabad 500007, Andhra Pradesh, India.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
A metal-free oxyacetoxylation method of primary, secondary and tertiary propargylic carboxylates with retention of chirality was presented. The reaction proceeds through the intramolecular nucleophilic attack of the neighboring carbonyl group on an alkynyliodonium intermediate. The process is general with broad substrate scope and is amenable for application to a variety of propargyl carboxylates including those obtained from natural products. Insight into the mechanistic pathway by isotopic labelling (using H2O18 and D2O) and controlled experiments confirmed.
Recommanded Product: 93-97-0. About Benzoic anhydride, If you have any questions, you can contact Pradhan, TR; Mohapatra, DK or concate me.
