Bis(p-methoxyphenyl)tellurone, the first definitely characterized tellurone, has been prepared by periodate oxidation of the Corresponding telluroxide and its oxidizing properties have been studied.
A Pd-catalyzed cascade Ullmann coupling–aldol–dehydration reaction of ortho-acylphenyl iodides affords colchino analogues with wide functional group tolerance.
A domino Pd-catalyzed reaction of 1-(2-bromophenyl)ethanones for the synthesis of novel 7-methyl-5H-dibenzo[a,c][7]annulen-5-ones, a carbon core structure present in colchicinoid natural products, is presented. The reaction is proposed to proceed via intermolecular homobiaryl coupling and intramolecular aldol condensation.
