We explored the bioinspired o-quinone cofactor catalyzed aerobic primary amine dehydrogenation for a cascade olefination reaction with nine different methyl N-heteroarenes, including pyrimidines, pyrazines, pyridines, quinolines, quinoxolines, benzimidazoles, benzoxazoles, benzthiazoles, and triazines. An o-quinone catalyst phd (1,10-phenanthroline-5,6-dione) combined with a Br?nsted acid catalyzed the reaction. N-Heteroaryl stilbenoids were synthesized in high yields and (E)-selectivities under mild conditions using oxygen (1 atm) as the sole oxidant without needing transition-metal salt, ligand, stoichiometric base, or oxidant.
1,2-dibromotetrachloroethane: An ozone-friendly reagent for the in situ Ramberga-Baecklund rearrangement and its use in the formal synthesis of E-resveratrol

Dibromotetrachloroethane (C2Br2Cl4) is demonstrated as a halogenating reagent for the one-pot conversion of sulfones to alkenes by way of the Ramberga-Baecklund rearrangement. Dibromotetrachloroethane successfully replaces known ozone depleting agents CCl4, CBr2F2 and C2Br 2F4. A formal synthesis of E-resveratrol is demonstrated using C2Br2Cl4.
