摘要

During attempts to synthesise the 2-hydroxy-1, 4-naphthoquinone, parvaquone, 1, a novel chromium-mediated method for the synthesis of functionalised β-lactones from propargyl alcohols has been discovered. Additionally, using both dry state and ultrasound conditions, the total synthesis of parvaquone (1) has been achieved: the most efficient techniques deliver this target compound in up to 46% overall yield over, as low as, two synthetic ...
