Practical Synthetic Method for the Preparation of Pyrone Diesters: An Efficient Synthetic Route for the Synthesis of Dolutegravir Sodium

Organic Process Research and Development, 2019
A highly efficient and practical synthetic method for the preparation of pyrone diesters was established. The pyrone diester 3c can be prepared from readily available starting materials on a multihundred gram scale.

NMR spectra of 2‐pyrone and 2‐pyrone derivatives

Journal of Heterocyclic Chemistry, 1969
AbstractAn analysis of the complex NMR spectrum of 2‐pyrone is presented and the spectra of a series of variously substituted 2‐pyrones and 5,6‐dihydro‐2‐pyrones are discussed. It is demonstrated that NMR spectroscopy affords a convenient and reliable method of assigning the position of substituents on the 2‐pyrone nucleus.

Pyrones as bacterial signaling molecules

Nature Chemical Biology, 2013
Bacteria communicate via small diffusible molecules and thereby mediate group-coordinated behavior, a process referred to as quorum sensing. The prototypical quorum sensing system found in Gram-negative bacteria consists of a LuxI-type autoinducer synthase that produces N-acyl homoserine lactones (AHLs) as signals and a LuxR-type receptor that detects ...
