Convergent Synthetic Route to Pyrano[2,3-a]carbazole by Multicomponent Reaction
摘要:
NaHCO3 has been found to be an efficient base catalyst for the synthesis of pyrano[2,3-a]carbazoles from 1-hydroxycarbazoles by multicomponent reaction using solvent-free grinding methods. In this case, the products have been found in good yields, without formation of any side product.
