In this work, a beneficial approach for efficient depolymerization of lignin and controllable
product distribution is provided. Lignin, an abundant aromatic biopolymer, has the potential …

This work describes the synthesis of spiro derivative compounds in the presence of
nonmetallic catalysts and ultrasonic irradiation. These synthesized derivatives constitute an …

An improved procedure has been developed for synthesizing derivatives of spiroindole in 84–
87% yield by using catalytic amount of graphene oxide supported nickel oxide …

In this work, an efficient and sustainable procedure for the one-pot synthesis of
thiopyrimidine derivatives starting 1, 3-diketone cut off β-O-4 lignin precursors to create …

Pyrazolopyridine and isoxazolopyridine derivatives were synthesized in a one-pot
procedure from indan-1, 3-dione, aromatic aldehydes, and 1, 3-dimethyl-1H-pyrazol-5 …
