This review summarizes the current knowledge on lactones, a class of biologically active
natural products isolated from a wide range of living organisms. Butenolide, 5, 6 …

The 2‐pyrone moiety can be found in a large number of natural products with a wide range
of biological activities, including antibiotic, antifungal, cytotoxic, neurotoxic, phytotoxic, anti …

Trifluoromethylated triazoles and tetrazoles have emerged as increasingly important
heterocycles in pharmaceuticals, agrochemicals, catalysis, and materials. As a …

A new synthesis of functionalized 2 H-pyran-2-ones has been developed through N-
heterocyclic carbene-catalyzed formal [3+ 3] annulation of alkynyl esters with enolizable …

Pyrone moieties are present in natural products and can be synthesized by a diverse range
of synthetic methods, resulting in the formation of various derivatives through chemical …

Polymer-supported catalysts have emerged as one of the sustainable and cost-effective
alternatives in organic synthetic chemistry. We have developed the first polymer-supported …

Donor–acceptor substituted aromatic systems are highly regarded organic fluorophores with
unique photophysical and electrochemical properties. These molecules offer a wide range …

An effective green one-pot and catalyst-free synthesis of a series of novel 5-(thiophene-2-
