One‐pot synthesis of dihydro-1H-indeno[1,2-b] pyridines and tetrahydrobenzo[b] pyran derivatives using a new and efficient nanocomposite catalyst based on N‐butylsulfonate‐functionalized MMWCNTs-D-NH2

In this study, magnetic multi-walled carbon nanotubes were functionalized with polyamidoamine (PAMAM) dendrimers and modified with butylsulfonate to afford MMWCNTs-D-(CH2)4-SO3H. The synthesized nanocomposite (MMWCNTs-D-(C

An eco-benign and highly efficient access to dihydro-1H-indeno[1,2-b] pyridines in 2,2,2-trifluoroethanol

4-Aryl-4,5-dihydro-1H-indeno[1,2-b]pyridine derivatives are synthesized from both electron-deficient and electron-rich substrates in a fast, high yielding, and operationally simple protocol in 2,2,2-trifluoroethanol (TFE). The solvent (TFE) can be readily

Triflates promoted one-pot synthesis of functionalized unsymmetrical new dihydro-1H-indeno[1,2-B]pyridines through Hantzsch reaction under ultrasonic irradiation

Yb(OTf)3 and Sc(OTf)3 catalyzed efficient Hantzsch reaction via four-component coupling reactions of aldehydes, diketone, ethylacetoacetate and ammonium acetate at ambient temperature and medium was described as the preparation of py

Multicomponent one-pot solvent-free synthesis of functionalized unsymmetrical dihydro-1H-indeno[1,2-b]pyridines

A simple and efficient synthesis of 4-aryl-4,5-dihydro-1H-indeno[1,2-b]pyridine derivatives has been achieved via a four-component cyclocondensation of 1,3-indanedione, aromatic aldehydes, β-ketoesters and ammonium acetate in one-pot in the absence of cat
