摘要
A novel regioselective annulation of propargylic alcohols with simple carbazoles for the construction of [3,2,1-jk]carbazole scaffolds is described to be the first example of intermolecular synthesis of [3,2,1-jk]carbazoles from simple carbazoles. In situ synthesis of propargyl alcohols from simple, cheap, and easily accessible ketones has also been developed during the one-pot synthesis of [3,2,1-jk]carbazoles. ??? R1 ??? Facile access to raw materials ??? Ligand-, Base-, and Silver-free reaction ??? One-pot tandem reaction ??? Up to 97% isolated yield, grain scalable R2,` R3 Pd/C R1 AromatIzatl n R1
