I found the field of Chemistry very interesting. Saw the article Organocatalytic Desymmetrisation of Fittig’s Lactones: Deuterium as a Reporter Tag for Hidden Racemisation published in 2019. Formula: C14H10O3, Reprint Addresses Soos, T (corresponding author), Res Ctr Nat Sci, Inst Organ Chem, Magyar Tudosok Korutja 2A, H-1117 Budapest, Hungary.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
Highly enantioselective desymmetrisation of Fittig’s lactones with alcohols is promoted by bifunctional cinchona squaramides. The reactions were carried out with monodeuterated methanol to detect possible hidden racemisation of the stereogenic centre. Current evidence suggests that racemisation was not a relevant process for most substrates; partial erosion of enantioselectivity was only detected with ortho-substituted aryl derivates. The resultant glutaric acid derivatives possess a scaffold that is common in natural products and the compounds are also useful chiral building blocks for further synthetic endeavours.
About Benzoic anhydride, If you have any questions, you can contact Spranitz, P; Soregi, P; Botlik, BB; Berta, M; Soos, T or concate me.. Formula: C14H10O3
