I found the field of Chemistry very interesting. Saw the article Design, synthesis and application of spiro[4.5]cyclohexadienones via one-pot sequential p-hydroxybenzylation/oxidative dearomatization published in 2021.0. Formula: C9H10O3, Reprint Addresses Chegondi, R (corresponding author), CSIR Indian Inst Chem Technol CSIR IICT, Dept Organ Synth & Proc Chem, Hyderabad 500007, Andhra Pradesh, India.; Chegondi, R (corresponding author), Acad Sci & Innovat Res AcSIR, Ghaziabad 201002, India.. The CAS is 120-14-9. Through research, I have a further understanding and discovery of 3,4-Dimethoxybenzaldehyde
One-pot sequential p-hydroxybenzylation/oxidative dearomatization/spiroannulation has been designed for the efficient construction of tetrahydrofuran containing spiro-cyclohexadienones. This reaction proceeds through the p-hydroxybenzylation of 1,3-diketones with p-hydroxybenzyl alcohol via quinone methide formation followed by oxidative dearomatization/spiroannulation with suitable alcohols. The Friedel-Crafts alkylation of spiro[4.5]cyclohexadienones with indoles provided a broad array of highly diastereoselective C-3 alkylated spirocycles and cyclohepta[b]indoles depending upon the ring size of the fused cyclic ketones.
Formula: C9H10O3. About 3,4-Dimethoxybenzaldehyde, If you have any questions, you can contact Patil, VB; Nanubolu, JB; Chegondi, R or concate me.
