I found the field of Chemistry very interesting. Saw the article alpha-Angelica lactone catalyzed oxidation of benzylic sp(3) C-H bonds of isochromans and phthalans published in 2020. Quality Control of Isobenzofuran-1(3H)-one, Reprint Addresses Das, U (corresponding author), CSIR Natl Chem Lab, Div Organ Chem, Pune 411008, Maharashtra, India.; Das, U (corresponding author), Acad Sci & Innovat Res AcSIR, Ghaziabad 201002, India.. The CAS is 87-41-2. Through research, I have a further understanding and discovery of Isobenzofuran-1(3H)-one
A metal-free organocatalytic system has been developed for highly efficient benzylic C-H oxygenations of cyclic ethers using oxygen as an oxidant. This oxidation reaction utilizes alpha-angelica lactone as a low cost/low molecular weight catalyst. The optimized reaction conditions allow the synthesis of valued isocoumarins and phthalides from readily available precursors in good yields. Mechanistic studies indicate that the reaction pathway likely involves a radical process via a peroxide intermediate.
