Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Benzochromanone and Benzochromene Natural Products: Synthetic Strategies and Total Syntheses

The Chemical Record, EarlyView.
This work outlines synthetic strategies for natural products with benzochromanone and benzochromene cores. Key achievements include total syntheses of xanthones, blennolide C, gonytolide C, and teretifolione B. Spirochromanone intermediates, benzyne–furan Diels–Alder reactions, and enzymatic resolution enabled efficient and enantioselective access to ...
