We report an efficient and highly diastereoselective protocol for the rapid construction of 3-nitro substituted 4-chromanones by an intramolecular Michael-type cyclization of α-nitro aryl ketones bearing unsaturated ester units. A catalytic amount of KOtB

2,3-Disubstituted benzofuran derivatives were synthesized from ortho-acylphenols in two steps. The β-aryloxyacrylates prepared from the ortho-acylphenols were treated with n-Bu3SnH/ AIBN and then with 5% HCl-EtOH to afford 2,3-disubstituted benzofurans. Georg Thieme Verlag Stuttgart.
Esters of 2,3-dihydro-3-oxobenzofuran-2-acetic acid and 3,4-dihydro-4-oxo-2H-1-benzopyran-3-acetic acid by intramolecular Stetter reactions

Intramolecular Stetter reaction of methyl 3-(2-formylphenoxy)prop-2-enoate catalyzed by 3-benzyl-5-(2-hydroxyethyl)-4-methyl-1,3-thiazolium chloride in refluxing dimethylformamide gave methyl 2,3-dihydro-3-oxobenzofuran-2-acetate in 39% yield. The presenc
