A facile route to isoflavone quinones via the direct cross-coupling of chromones and quinones.
A straightforward and efficient method for the palladium-catalyzed direct cross-coupling of chromones with various quinones has been developed to rapidly construct isoflavone quinone structural motifs.
متن کاملDirect use of allylic alcohols in the allylation of sulfonylimidates.
We have developed catalytic allylation reactions of sulfonylimidates using allylic alcohols as allylating reagents. Stoichiometric amounts of neither activators nor bases are required in this reaction.
متن کاملStereocontrol in synthesis of homoallylic amines. Syn selective direct allylation of hydrazones with allylboronic acids.
Allylboronic acids directly react with acyl hydrazones, affording homoallylic amine derivatives. The reaction proceeds with very high syn selectivity, which is the opposite of the stereochemistry observed for allylboration of imines. The reaction can be carried out with both aromatic and aliphatic acyl hydrazones. Based on our studies the excellent syn stereochemistry can be explained by chelat...
