Highly efficient and recyclable basic mesoporous zeolite catalyzed condensation, hydroxylation, and cycloaddition reactions

Sarmah, B.; Satpati, B.; Srivastava, R. (2017-05-19)

Crystalline mesoporous ZSM-5 zeolite was prepared in the presence of 1,4-diazabicyclo[2.2.2]octane derived multi-cationic structure directing agent. The calcined form of the mesoprous zeolite was treated with NH4OH to ...
Synthesis of functionalized dispiro-oxindoles through azomethine ylide dimerization and mechanistic studies to explain the diastereoselectivity

Banerjee, P.; Pandey, A.K. (2016-11-23)

We have developed a one-pot synthesis of polycyclic fused dispiro-oxindole derivatives by the [3 + 3]-cycloaddition (dimerization) of azomethine ylide derived from condensation of isatin and proline. The dispiro-oxindole ...
