Louisianin A (1) was treated with phosphoryl chloride (POC13) at 120~ 125°C3) to obtain chloro derivative (2) in 86% yield. 2 was reduced by Zn-AcOH at 50°C4) to afford 3 (52% yield) and 4 (35% yield). Furthermore, under the same condition, 3 was dechlorinated to give 4 in 48% yield. Moreover, 4 was oxidized in the treatment of CrO3-pyridine5) to obtain louisianin C (5) in 75% yield. Finally, 5...
