Novel Skeleton Transformation Reaction of α‑Pyrone Derivatives to Spirobicyclo[3.1.0]hexane Derivatives Using Dimethylsulfoxonium Methylide

, 2016
By applying a skeleton transformation reaction using dimethylsulfoxonium methylide, a novel reaction was identified by which 5,6,7,8-tetrahydrocoumarin with the electron-withdrawing group at C3 was led to the spirobicyclo[3.1.0]hexane-cyclohexane ...

Tribological analysis of a novel lubricant additive: Pyrone esters

, 2019
This work evaluates the friction and anti-wear properties under boundary lubrication of novel lubricity additives derived from 2-pyrone. Pyrone Esters (PEs) of varying carbon chain lengths were synthesized by reacting coumalic acid chloride with alcohols.
