The one-pot reactions of acyl chlorides, Wittig reagents, and o-iodoanilines involving a copper-catalyzed C–C coupling have been realized to provide various indoles. The reactions proceed on the basis of the in situ generation of allenes to incorporate o-iodoanilines via tandem Michael addition, C–C coupling, and tautomerization to afford indoles. This direct one-pot protocol allows the synthesis...
A new three-component reaction among o-phthalaldehyde, N-alkyl/aryl substituted urea, and an aromatic aldehyde has been developed at ambient condition, and a class of isoindolinones with novel C-3 substitution were conveniently synthesized. The general diastereomeric excess as high as over 99% of the products indicated the excellent stereoselectivity posed in this multicomponent reaction.
